A ball is throwm upword with an initial velcoity o f`100 ms^(-1)`. After how much time will it retun ? Draw velcoity - time graph for the ball and find from the graph (i) the maximum height attained by the ball and (ii) height of ball after 15 s. take g = `10 ms ^(-2)`.

A ball is thrown upward with an initial velocity of 80 ms^(-1) . After how much time will it return to ground ? Draw velocity-time graph for the ball and find from the graph (a) the maximum height attained by ball and (b) height of the ball after 12 s . Take g=10 ms^(-2) .

A ball is thrown upward with an initial velocity of 100 ms^(-1) . After how much time will it return ? Draw velocity-time graph for the balland find from the graph : height of the ball after 15 s. Take g = 10 ms^(-2)

A ball is thrown vertically upwards with a velocity of 10 ms^(-1) . It returns to the ground with a velocity of 9 ms^(-1) . If g=9.8 ms^(-2) , then the maximum height attained by the ball is nearly (assume air resistance to be uniform)

A ball is thrown up at a speed of 4.0 m/s. Find the maximum height reached by the ball. Take g=10 m//s^2 .

A ball is thrown vertically upwards with a velocity of 20 ms^(-1) from the top of a multistorey building. The height of the point from where the ball is thrown is 25 m from the ground. How long will it be before the ball hits the ground (Take, g=10 ms^(-2) ) ?

The maximum height attained by a ball projected with speed 20 ms^(-1) at an angle 45^(@) with the horizontal is [take g = 10 ms^(-2) ]

A ball is thrown vertically upwards with a velcotiy of 20 ms^(-1) from the top of a multi-storey building. The height of the point fromwher the ball is thrown if 25-0m from the ground. (a) How high the ball will rise ? And (b) how long will it be before the ball hits the ground ? Take. g=10 ms^(-2) .

A steel ball is dropped on a hard surface from a height of 1m and rebounds to a height of 64cm . The maximum height attained by the ball after n^(th) bounce is (in m)
