Gravity is what causes the ball to accelerate. The acceleration of the ball during the entire time it is in the air, assuming it is on the Earth's surface, is 9.8 m/s2.
In a simple scenario, the ball falls in accordance with the direction of gravity, which is always downward. Gravitational acceleration on Earth is 9.8 m/s2 (g=9.8 m/s2). In essence, this indicates that the ball's velocity will increase by 9.8 m/s for every second while it is falling.
The bowling ball accelerates at 1.875 m/s2.
The ball revolves around its center of gravity while in flight. The center of gravity's motion is described by Newton's laws of motion. Drag is the term for the force that the air exerts on the motion of the ball as it travels through it.
force
According to Newton's second law, a large body will accelerate, or change its velocity, at a constant rate, when a constant force is applied to it. In the most basic scenario, when a force is applied to an object at rest, it accelerates in the force's direction.
Distance, time, acceleration, and velocity relationships. Unfortunately, the golf ball would stop accelerating unless we had a rocket-powered golf ball. It would merely move roughly in the horizontal direction at a constant speed.

The dimension of b and c is and
Since the x axis may be determined from the expression that shown below.
Here, x will be in meters when t is in seconds
Now
Here the dimension of the right side should be equivalent to the left side.
According to the left side the dimension should be same like length or meter so same goes for the right side
So,
Now for another one it is

As per given equation we have
now as per the dimensional analysis we can say that dimension of right side of equation must be equal to left side of the equation
now as per left side of equation its dimension is same as length or meter
now we can say it should be meter on right side also
similarly for other term we have
so above are the dimensions of b and c
pitch
frequency
wavelength
Answer:
a) = -30 m/s
b) = 30 m/s
Explanation:
a)
Consider the car A travel at a velocity of = 90 km/h and the car B travel at the velocity of = 120 km/h. As the velocity of the car B is greater than the car A, So it cross the car A. Consider The velocity of car A relative to car B is and it is equal to the velocity of car A minus the velocity of car B.
= -
= 90 - 120
= -30 m/s
b)
Consider The velocity of car B relative to car A is and it is equal to the velocity of car B minus the velocity of car A.
= -
= 120 - 90
= 30 m/s
Answer:
Tides are the rise and fall of sea levels. Tides occur due to the gravitational forces exerted on the Earth by moon, and to a lesser extent, the sun. That's why tides occur in ocean or sea.
