Question

Boxes are transported by a conveyor belt with a velocity vo to a fixed incline at A, where they slide and eventually fall off at B. Knowing
that μk = 0.40, determine the velocity of the conveyor belt if the boxes leave the incline at B with a velocity of 11 ft/s.
20 ft
15°
The velocity of the conveyor belt is 4.08 ft/s 15°.

You are in charge of a cannon that exerts a force 17100 N on a cannon ball while the ball is in the barrel of the cannon. The length of the cannon barrel is 2.37 m and the cannon is aimed at a 36.7 ◦ angle from the ground. The acceleration of gravity is 9.8 m/s 2 . If you want the ball to leave the cannon with speed v0 = 89 m/s, what mass cannon ball must you use? Answer in units of kg. Answer in units of kg.
Two crates of fruit are released from the top of a ramp inclined at 30 degrees from the horizontal and 4.5 meter long. The two crates consist of an apple crate of mass 20 kg that is placed in front of a watermelon crate of mass 80 kg. The apple crate has a coefficient of friction of 0.20 while the watermelon crate has a coefficient of friction of 0.15. How long does it take the apple crate to reach the bottom of the incline if it needs to travel a distance of 4.5 meters?

Consider a waterslide that has a vertical drop of H1. At the bottom of the slide the person is leaving the slide horizontally, where the end of the slide is h2 above the water. Ignore friction and air resistance to find the distance, L, from the end of the slide a person will land in terms of H1 and h2.
