Q. A 3.10 kg steel ball strikes a wall with a speed of 10.0 m/s at an angle of 60.0° with the surface. It bounces off with the same speed and angle. If the ball is in contact with the wall for 0.190 s, what is the average force exerted on the ball by the wall?
Q. A flight attendant pulls her flight bag a distance of 267 m along a level airport floor at a constant speed. The force she exerts is 32.0 N at an angle of 52.0° above the horizontal. Find the work she does on the flight bag.
An archer pulls her bow string back 0.40m by exerting a force that increases uniformly from zero to 25 N. How much work does the archer do in pulling back the bow.
An 845-N sled is pulled a distance of 173 m. The task requires 1.20 x 10^4 J of work and is done by pulling on a rope with the force of 142 N. At what angle is the rope held.
A 1050 kg car carrying four 84 kg people travels over a rough "washboard" dirt road with corrugations 4m apart which causes the car to bounce on its spring suspension. The car bounces with maximum amplitude while its speed is 24km/h. The car now s..
