What is force of inertia?????????

The force of inertia is the property common to all bodies that remain in their state, either at rest or in motion, unless some external cause is introduced to make them alter this state.

A place kicker must kick a football from a point 36.0 m from the uprights. As a result of the kick, the ball must clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with an initial speed of 20 m/s at an angle of 53° to the horizontal. By how much does the ball clear or fall short of clearing the crossbar?

Answers

Final answer:

By utilizing principles of projectile motion, it is found that the football clears the crossbar by approximately 10.75 meters.

Explanation:

To determine by how much the ball clears or falls short of clearing the crossbar, we need to use the physics principles of projectile motion. The maximum height 'h' of the football can be given by equation of motion: h = (v²sin²θ) / (2g), where 'v' is the initial velocity, 'g' is the acceleration due to gravity and 'θ' is the angle of projection.

Substituting the given values: h = [(20)²sin²53°] / (2*9.8) ≈ 13.8 m above the ground when it was kicked. However, the football was kicked from ground level, so we need to subtract the height of the crossbar from this value, which is 3.05 m. Thus, the ball clears the crossbar by approximately: 13.8 - 3.05 = 10.75 m.

The energy of motion is calledA. kinetic energy.
B. potential energy.
C. thermal energy.
D. work.

Answers

A. kinetic energy.

Friction converts kinetic energy into heat, and so it represents a net loss of mechanical energy. When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into heat. As demonstrated by the use of friction created by rubbing pieces of wood together to start a fire, kinetic energy is converted to heat whenever motion with friction occurs. The friction produced by brake pads in a car must generate a quantity of heat equal to the kinetic energy of the car and as a result, the brakes get quite hot.

Answers

Answer: hello options related to your question is missing attached below is the missing part of your question

answer: No charge of the length of the bonds expected because the rod did not touch the charge source ( option A )

Explanation:

When the Charge is first, Furthest away and second and closest to the source charge. The spring like bonds can be said to have No charge of the length of the bonds expected because the rod did not touch the charge source when Furthest away the bond with charge will be less effective

Two asteroids bump in space. The larger one has a mass of 3000 kg and the smaller one has a mass of 100 kg. If the force of the collision is 10,000 newtons on each asteroid, what are their accelerations?a. The larger one is unaffected by the collision, while the smaller one accelerates at 100 m/s2.
b. The larger one accelerates at 3.33 m/s2, while the smaller one accelerates at 100 m/s2.
c. The larger one accelerates at 100 m/s2, while the smaller one accelerates at 3.33 m/s2.
d. The ...

Answers

Answer:

B) The larger one accelerates at 3.33 m/s² while the smaller one accelerates at 100 m/s².

Explanation:

Parameters given:

Mass of larger asteroid = 3000 kg

Mass of smaller asteroid = 100 kg

Force of collision = 10000 N

Since both of them experience the collision force, we can find how that force causes them to accelerate by using the formula of force:

F = m*a

=> a = F/m

For the larger one,

a = 10000/3000 = 3.33 m/s²

For the smaller one,

a = 10000/100 = 100 m/s²

There's really no such thing as the force of a collision.

F = M A
A = F / M

If a 10,000N net force acts on a 3,000 kg object, then the object's
acceleration is (10,000N / 3,000kg) = 3-1/3 m/s² for as long as the
force on it persists, and zero after that.

If a 10,000N net force acts on a 100 kg object, then the object's
acceleration is (10,000N / 100kg) = 100 m/s² for as long as the
force on it persists, and zero after that.

Those appear to be the numbers in choice-b, but the description
of the event and the situation is misleading.
