A 3.0 kg crate slides down a 1-meter long ramp which is 0.5 m high, and makes an angle of 30° with the floor. The crate starts from rest at the top of the ramp and experiences a constant frictional force of 5.0 N as it slides down. Calculate the speed of the crate as it reaches the bottom of the ramp.

A 2.0-kg mass is released from rest at the top of a plane inclined at 20o above horizontal. If there is no friction, what will be the speed of the mass after sliding 4.0 m along the plane?

Coefficient of kinetic friction between the mass and the incline 0.2. Find the minimum work done to slide the mass from the bottom to the top of the incline. F, = 50 N 10 kg h = 4 m 0 = 30

In a physics lab, a pendulum hung from the ceiling swings back and forth. Select the arrow pointing closest to the direction of the net force (sum of all forces) acting on the pendulum bob when it is at its lowest at point C. 25 Hm A Heiga so H2 H2 = v C H2 =1 F so option C E 2. W = Force" W = mas G Zero net force since mass is do O A Work also doublee OB Work Done by cons so False it is O D O E O F 3. due to the law of cons OG one form of energy disapE so But not non mehanical fo P Type here to search Bb
