QUESTION 1

If the Rams receiver (White shirt, blug pants) has a mass of 83 kg and is running at 5.1 m/s, what speed doe the Falcon's defender (red shirt, white pants) have to be running to stop him dead in his tracks if he has a mass of 106 kg? Assume answer is positive (speed, not velocity). Leave answer to 1 decimal place and no spaces between answer and units. What is the velocity of the boy holding the white ball after collision if the following is true: Mass of boy with blue ball 1: 95 kg Initial Velocity of boy with blue ball 1: 5 mis Mass of boy with blue ball 2: 79 kg Initial Velocity of boy with blue ball 1: 8 m/s Mass of boy with purple ball: 84 kg Initial Velocity of boy with purple ball: 5 m/s Mass of boy with White ball 1: 60 kg Initial Velocity of boy with white ball: -6 m/s (moving in opposite direction) Assume the 3 other boys are not moving after collison Leave the answer to one decimal places and have no spaces between answer and units. (In reality this is a transfer of elastic energy to kinetic energy problem, but for this practice it is a conservation of momentum and all movement is in 1 plang) If a ball has a maximum displament of 64 and a maximum height of 99, what was its initial angle of raleasa? Use -10 m/s= for acceleration. Leave no units. Leave the answer to zero decimal places How much tension is the the rapelling rope if the person has a mass of 75 kg and the angle of the rope with respect to the cliff is 25 degrees. You may assume the gravitational constant is 10 m/ 2 Leave answer to zero decimal places and leave no spaces between the answer and the units
