[ The momentum of a 3000 kg truck is 6.36 x 10" kg'm/s. At what speed is the truck traveling? A 0.40 kg object is moving on a frictionless surface with a speed of 30 m/s. A force of 20 N is applied continually until the velocity of the object has been reversed. How long was the force applied? A 0.058-kg golf ball is struck by a club that produces a force of 272 N and gives the ball a velocity of 62 nm/s. For how long was the club in contact with the ball? A force of 186 N acts on a 7.3-kg bowling ball for 0.40 s. What is the change in velocity of the bowling ball? Small rockets are used to make tiny corrections to the speed of a satellite. If a rocket has a thrust of 35 N and is used to change the velocity of a 72000-kg satellite by 63 cm/s, for how long should it be fired
