A small ball of 0.1 kg is flying towards a person and the person
uses a bat to hit the arriving ball. An impulse 3𝑖̂+ 0.3𝑗̂N ⋅ s
acts on the ball. Just before the hit, the ball is moving at a
velocity −10𝑖̂− 0.1𝑗̂m/s, 1 m from the ground. (a) Find the
velocity of the ball just after the hit, in magnitude-angle
notation. (6 marks) (b) Find the landing time after the hit and the
horizontal landing distance from the hit. (9 marks)
