For the above data, what is the acceleration of block?
A boy throw a ball upwards with velocity v0 = 20 m/s . The wind imparts a horizontal acceleration of 4 m/s2 to the left.
The angle θ at which the ball must be thrown so that the ball returns to the boy's hand is ( g = 10m/s2 )
If we throw a body upwards with velocity of 4ms−1 at what height its kinetic energy reduces to half its initial value ? Take g=10m/s2
