A ball is thrown upwards from the ground with an initial speed of u. The ball is at height of `80m` at two times, the time interval being 6 s. Find u. Take `g=10 m//s^2.`

A ball is thown upwards from the ground with an initial speed u. The is at a height of 80 m at two times, the interval being 6s. Find the value of u.

A ball is thrown upwards from the top of a tower 40 m high with a velocity of 10 m/s. Find the time when it strikes the ground. Take g=10 m//s^2.

A ball is thrown vertically upwards from the ground with a velocity of 24.5 m/s . If g=9.8 m/s^2 , then the ball will be at a height of 29.4 metres from the ground after time

A ball 'A' is thrown upwards from ground level with a velocity of 20 ms^(-1) . Another ball 'B' is thrown downwards from a height of 40 m with the same speed. Find the height at which the two balls meet (take g = 10 m s^(-2) ).
