5. How fast must an 816 kg Volkswagen travel to have the same momentum as a 2650 kg Cadillac going 16.0 km/hr'? 6. A 55 kg beach-goer attempts tojump on to a stationary 1.5 kg skim board. a. What is the velocity of the person + skimboard if the person has an initial velocity of 2.25 m/s? b. Suppose the skim board had an initial velocity of +1.75 m/s. What is the new velocity of the person on the skim board immediately afterjumping on? 7. The bumper of a new car is being tested. The 2300 kg vehicle, moving at 15 m/s is allowed to collide with the bumper and comes to rest after 0.54 seconds. What is the average force acting on the bumper during impact?
