3. A cat is trying to jump onto a countertop that is 1m tall from 0.3m away. The cat's initial jump speed (magnitude of the total initial velocity) is 10m/s. To land on the counter 0.1m from the edge, at what angle should the cat jump?
If a freight train can accelerate at 0.050 m/sec2, how far must it travel to increase its speed fro 2.0 to 8.0 m/sec?
A 36.0 kg uniform beam is attached to a wall with the hinge while its far end is supported by a cable such that the beam is horizontal.
Because of your knowledge of physics, you head your boat 44° west of north and have a velocity of 8.0 m/s due north relative to the shore. Illustrate w hat is the velocity of the current? What is your speed relative to the water.
Find the difference in decibel levels β1 & β2 of a sound source is related to the ratio of its distances r1 & r2 and find the average power generated by the horn.
