A ball of weight 200g accelerates at 40m/s from rest along a straight line path , Distance travelled by ball is 2meter in 20 seconds. Find the force applied and final velocity of ball . (Drive the formula )
2) Ram and Sham have 2 balls , Ram has a ball of 100g and Sham has a ball of 200g .Both throw ball along a straight line, Initial Velocity of ball of 100g was noticed 50m/s after 2 min , and Initial Velocity of ball of 200g was noticed 40m/s after 3min .If final velocity of ball of 100g was 20m/s then find the final velocity of ball of 200g.
(nothing to do with time , drive formula feom newtons 3rd law)
