Chapter 8, Problem 44PE

(a) During an ice skating performance, an initially motionless 80.0-kg clown throws a fake barbell away. The clown's ice skates allow her to recoil friction-lessly. If the clown recoils with a velocity of 0.500 m/s and the barbell is thrown with a velocity of 10.0 m/s, what is the mass of the barbell? (b) How much kinetic energy is gained by this maneuver? (c) Where does the kinetic energy come from?

A 4.0 kg box slides on a horizontal frictionless table and collides with a 1.6 kg box initially at rest on the edge of the table, at height h = 1.0 m. The speed of the 4.0 kg box is 3.6 m/s just before the collision. If the two boxes stick together because of packing tape on their sides, what is their kinetic energy just before they strike the floor? (Your result must be in Joules and include 1 digit after the decimal point. Maximum of 2% of error is accepted in your answer. Take g=9.8 m /s 2.)

A 0.450 kg ball of Play-Doh hangs from the ceiling by a string. A 0.0850 kg wad of Play-Doh is thrown straight upward from below the ball and strikes the ball with a speed of 5.60 m/s and sticks to it. (a) Is the mechanical energy of this system conserved? Yes No (b) How high (in cm) does the combined mass of Play-Doh rise above the original position of the ball of Play-Doh? X Since the collision takes place over a very short time interval, we may conserve linear momentum to obtain the speed of the combined mass right after the collision. Knowing the speed of the combined mass the instant after the collision, see if you can use your knowledge of kinematics to determine how high the combined mass rises above the original position of the ball of Play-Doh. cm

Hello, here is my question A spring with spring constant k = 3.75 N/cm is compressed 7.00 cm. A 1.50 kg mass is placed next to the compressed spring. When the spring is released, this mass moves without friction and collides with a stationary mass of 2.00 kg. The two masses stick together and move without friction up a slope angled at 20.0 degrees. (a) (10 points) How far along the slope does the two-mass system travel? (b) (5 points) If it takes 5.00*10-3 seconds from the initial impact for the two masses to stick together, what is the magnitude of the average contact force between the two blocks? (c) (5 points) The two-mass system will slide back down the slope and compress the spring. What is the spring’s maximum compression? Thank you!
