What is the velocity of the car, in meters per second, just after it hits a 135-kg deer initially running at 10.5 m/s in the same direction? Assume the deer remains on the car.

True or false the metric unit used to describe weight as a measure of the force of gravity is called a newton

One car travels 40. meters due east in 5.0 seconds, and a second car travels 64 meters due west in 8.0 seconds. During their periods of travel, the cars definitely had the same

When an object slides down an inclined plane, the angle between the displacement and the force of gravity is the same as the angle that the surface makes with the horizontal. Suppose you have a 2-kg cart rolling a distance of 1.
