Question 1 F (ms) A 55.0 g golf ball, initially at rest, is hit by a golf club. The force-verses-time graph for the impact on the ball is shown below, where Fmax = 650. N. What is the speed of the golf ball just after the impact? O 2.60 m/S 47.3 m/s 23.6 m/s O 0.0473 m/s Question 2 A 4.00 kg object, travelling at 5.10 m/s to the right, suddenly explodes into two pieces. The 1.60 kg piece moves to the right at 7.80 m/s after the explosion; What is the speed of the 2.40 kg piece? O 8.22 m/S 3.30 m/S 4.95 m/S O 13.7 m/s Question 3 A missile is fired form the back of a stationary truck. The missile takes off at a speed of 47.5 m/s and has a mass of 62.0 kg. If the truck has a mass of 1.14x10 kg, what is the recoil speed of the truck? O 2.58 m/s O 22.7 m/s 2.45 m/S O 1.31 m/s
