QUESTION 1 Randy Johnson is going to throw a fast ball (1.1 kg). If Randy exerts an average force of 76 N for 0.8 seconds, at what velocity does he release the ball? Leave no spaces between answer and units. Leave to 1 decimal place. QUESTION 2 Steph Curry (107 kg) lands on the ground with an initial velocity of 7.7 m/s downward. 0.5 = later, he is lzaving the ground with a velocity of 3.8 m/s upward. What average force did Curry experience during this transition? Leave anwer to no decimal places and no spaces between the answer and units. Use g= 10m/ss (if needed) QUESTION 3 Steph Curry {108 kg) lands on the ground with an initial velocity of 8.7 m/s downward. 0.9 = later, he is leaving the ground with a velocity of 3.6 m/s upward. What average force did the floor exert during this fransition? Leave anwer to no decimal places and no spaces between the answer and units. Use g= 10m/ss (if needad) QUESTION 4 Randy Johnson is going to throw a fast ball (0.9 kg). If Randy exerts an average force of 377 N for 0.7 meters before release, at what velocity does he release the hall? Leave no spaces between answer and units. Leave to 1 decimal place. QUESTION 5 Acsemi with a mass of 1441 kg and going at a velocity of 80 m/s and hits a parked car{572 kg) at rest. If all the momentum is transfered to the car (the semiis now at rest), at what speed does the car move forward (assume an elastic collison, no decimals in the answer and leave no spaces between units and answer). L ] QUESTION & A 131 kg defensive lineman is running at a 79 kg running back at a speed of 1 m/s. If the running back is running at the lineman with a velocity of 7 mis (assume this one is negative) and the two collide (assume inelastic collision), what is the final velocity of the lineman/running back comba? (One decimal place and no spaces between units and answer) I QUESTION 7 Mike Piazza is catching a baseball (0.8 kg) from his pitcher If the baseball is moving at 25 m/s when it hits the glove and Mike exerts 1439 N against the hall to stop it, how far does his hand move back? Leave answer to 2 decimal places and no spaces between answer and units. L ]
