0.79m/s, 0.53m/s) 7. A 3.0 kg crate slides down a ramp. The ramp is 2.0 m in diagonal length and inclined at an angle of 30.0°. The crate starts from rest at the top, experiences a constant friction force of magnitude 5.0 N, and continues to move a short distance on the horizontal floor after…
5. A pendulum used in a physics experiment swings back and forth. A motion detector records the position and velocity of the pendulum as it swings back and forth. Sketch an approximate graph of velocity versus time for the pendulum. Label the points that correspond to the highest and lowest…
3. What needs to be true in order for mechanical energy to be conserved? 4. A ride at the new Disney theme park is illustrated below. The car with passengers has a total mass of 1350 kg. At the top of the 15m high hill, it is travelling at 4.2 m/s. It rolls down a frictionless hill and…
