Unformatted text preview: Physics Worksheet Unit 6.0 1. A deer with a mass of 146 kg is running head on toward you with a speed of 17 m/s. You are going north. Find the momentum of the deer. 2. A .5 kg football is thrown with a velocity of 15 m/s to the right. A stationary receiver catches the ball and brings it to rest in .02 seconds. What is the force exerted on the ball by the receiver? 3. A 2500 kg car traveling to the north is slowed down uniformly from an initial velocity of 20 m/s by a 6250 N braking force acting opposite the cars motion. (Hint force is negative 6250 not positive). Use the impulse momentum theorem to answer the following questions: a. What is the cars velocity after 2.5 s? b. How far does the car move during 2.5 s? c. How long does it take the car to come to a complete stop (final velocity now equals zero)? 4. A 63 kg astronaut is on a spacewalk when the tether line to the shuttle breaks. The astronaut is able to throw a spare 10 kg oxygen tank in a direction away from the shuttle with a speed of 12 m/s, propelling the astronaut...
