A mechanic test driving a car that she has just given a tune-up accelerates from rest to 50.0 m/s in 9.8 s. How far (in meters) does she travel in that time?

How can Ohm's Law relate to a house fire?

Which of the following statements describes how a heat pump works? 1. The heat pump decompresses gas to warm and cool air. 2. The heat pump compresses gas to warm air and decompresses gas to cool air. 3.

We claim that momentum is conserved. Yet most moving objects eventually slow down and stop. Can you explain.

A 26.2-kg dog is running northward at 3.02 m/s, while a 5.30-kg cat is running eastward at 2.74 m/s. Their 65.1-kg owner has the same momentum as the two pets taken together. Find the direction and magnitude of the owner's velocity.

A roller coaster car crosses the top of a circular loop-the-loop at twice the critical speed. What is the ratio of the normal force to the gravitational force?

A hiker leaves her camp and walks 3.5 km in a direction of 55° south of west to the lake. after a short rest at the lake, she hikes 2.7 km in a direction of 16° east of south to the scenic overlook.

A star has a mass of 1.36 x 1030 kg and is moving in a circular orbit about the center of its galaxy. the radius of the orbit is 2.1 x 104 light-years (1 light-year = 9.5 x 1015 m), and the angular speed of the star is 1.1 x 10-15 rad/s.

Floating in deep space, you find yourself at rest next to a small asteroid. You reach out and tap the asteroid with a hammer. What happens to you in this process?
