1. A batsman hits a cricket ball towards a fieldman who is 65m away. The ball reaches a maximum height of 4.9m and the horizontal component of its velocity is 28m/s. Find the constant speed at which the fieldsman must run forward, starting at the instant the ball is hit, in order to catch the ball at a height of 1.3m above the ground. (use g = 9.8)
Answer: 7m/s
2. Find the speed (v) and direction (angle of projection) of a particle which, when projected from a point 15m above the horizontal ground, just clears the top of a wall 26.25m high and 30m away.
Answer: 25m/s, 36'52''
Answer: 7m/s
