A tennis ball, starting from rest, rolls down the hill in the drawing. At the end of the hill the ball becomes airborne, leaving at an angle of `37^(@)` with respect to the ground treat the ball as a thin-walled spherical shell.
Q. Range `x` of the ball is

A

`(144)/(125)h`

B

`(48)/(25)h`

C

`(48)/(35)h`

D

`(24)/(7)h`

Text Solution

Verified by Experts

The correct Answer is:
A
`R=x=(2u^(2)sin37^(@)cos37^(@))/(g)`
`=((2)(6gh//5)(3//5)(4//5))/(g)`
`=(144)/(125)h`

A batter hits a pitched ball when the centre of the ball is 1.22 m above the ground. The ball leaves the bat at an angle of 45^(@) with the ground. With that launch, the ball should have a horizontal range (returning to the launch level) of 107 m. (a) Does the ball clear a 7.32-m-high fence that is 9.75 m horizontally from the launch point? (b) At the fence, what is the distance between the fence top and the ball center?

A tennis ball launcher is placed on the floor at the front end of a train that has a uniform forward acceleration of 2m/s^(2) .The launcher projects a ball at an initial speed of 20m/s with respect to the train toward its rear.The ball achieves a maximum height of 10.0m .Ignore air resistance.Find how far (in m) from the front end of the train the ball lands inside the train.

A tennis ball launcher is placed on the floor at the front end of a train that has a uniform forward acceleration of 2 m/s2. The launcher projects a ball at an initial speed of 20 m/s with respect to the train toward its rear. The ball achieves a maximum height of 10.0 m. Ignore air resistance. Find how far (in m) from the front end of the train the ball lands inside the train.

A ball of mass m is projected from ground making an angle q to the horizontal. There is a horizontal wind blowing in the direction of motion of the ball. Due to wind the ball experiences a constant horizontal force of (mg)/(sqrt(3)) in direction of its motion. Find theta for which the horizontal range of the ball will be maximum.

A soccer ball is kicked from the ground with an initial speed of 21.3 m/s at an upward angle of 45^(@) . A player 55 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground?
