Find the total force in Newtons if a 1500 kg car has k = 0.001 with the road, and accelerates with 4 m/s 2.

A wooden block is pulled at a constant acceleration of 1.6 m/s^2. Find the net applied force on the block if its mass is 0.8 kg.

What average net force is required to accelerate a 8.7 g bullet from rest to 700 m/s over a distance of 0.78 m along the barrel of a rifle? 

Briefly explain why you cannot hear sound in space in one or two sentences. You must use at least four of the following terms correctly (wave, vacuum, seismic, medium, mechanical, visible,... more

Calculate the kinetic energy contained in a 25 kg bicycle travelling at 10 m/s.

The generator at a power plant produces AC at 19,000 V. A transformer steps this up to 355,000 V for transmission over power lines. If there are 1,850 turns of wire in the input coil of the... more
