Answers
Answer:
- 70 kg
Explanation:
We know that,
- Kinetic energy = 1/2 mv²
Where m is mass and v is velocity or speed.
Putting the required values,
- 5040 = 1/2 × m ( 12 × 12)
- 5040 × 2 = m × 144
- 10080 = m × 144
divide both side by 144
- m = 70 kg
So the mass of the diver is 70 kg respectively.

d.Children acquire motor skills in the sequence implied by motor norms.
Answers
Answer:
(a) Motor skills are interrelated.
Explanation:
As per the question,
Motor development:
It is defined as the development of movement abilities such as the development of a child's bones, muscles and ability to move around and manipulate his or her environment.
Importance of a Motor Development Model are:
(1) Helps us make sense of developmental changes
(2) Provides a framework for observing the change
(3) Helps us include important factors of motor behavior in our observations.
Hence, Only option (a) is correct.

Hello!
A person pushing a stroller start from rest uniformly accelerating at a rate of 0.500 m/s². What is the velocity of the stroller after it traveled 4.75 m ?
We have the following data:
a (acceleration) = 0.500 m/s²
Vf (final velocity) = ? (in m/s)
Vi (initial velocity) = 0 m/s
Δx (displacement) = 4.75 m
Solving:
Let's apply the Torricelli Equation, to find the velocity of the stroller, let's see:
Answer:
The velocity of the stroller is approximately 2.18 m/s

According to her friends, with what speed was ball 2 thrown?
Answers
Final answer:
In the context of relative velocity, Ball 1 was thrown with a speed of 21 m/s and Ball 2 was thrown with a speed of 11 m/s according to her friends.
Explanation:
The problem presented involves the concept of relative velocity. The speed of the balls relative to Anita is 16 m/s and she is running at a speed of 5 m/s.
If ball 1 is thrown in the same direction as Anita is running, then the friends on ground would see the speed of the ball as the sum of its velocity relative to Anita and the speed of Anita. So, the speed of ball 1 would be 16 m/s + 5 m/s = 21 m/s. Ball 1 was thrown with a speed of 21 m/s according to her friends.
For Ball 2, if it's thrown in the opposite direction to which Anita is running, then according to her friends the speed of Ball 2 would be 16 m/s (speed of the ball relative to Anita) - 5 m/s (Anita's speed) = 11 m/s. Therefore, Ball 2 was thrown with a speed of 11 m/s according to her friends.

Acceleration due to Gravity:
Explanation:
Here g is acceleration due to gravity. So C. 3.8 m/s2
Answers
Answer:
v = 12,4 m/s
Explanation:
frictionless means all gravitational Energie (Eg) will be converted to kinetic Energie (Ek)
Ek = 0.5 * m * v^2
Ez = m * g * h
Ek = Ez
0.5 * m * v^2 = m * g * h
divide left and right of the = sign by m.
(This means that the final velocity is independent of the mass of both children !)
0.5 * v^2 = g * h
v^2 = 2 * g * h
v = +- SQRT (2 * g * h)
with
g = 9.8 m/s^2
h = 7,8 m/s
v = +- SQRT (2 * 9.8 * 7.8)
v = +- SQRT (152.88)
(v = - 12,4 m/s has no meaning in this case)
The velocity 7,8 m below the starting point, will be
v = 12,4 m/s

the answer is 336.96 mph
