A person is driving a car with a velocity v as shown below. Suddenly a force acts on the car for a short time giving rise to an acceleration also shown in the figure.  As a result of this acceleration, the speed of the car will ____________.   135 degrees on the graph  increase decrease remain the same  will increase but will eventually decrease

The average distance between Earth and the Sun is 1.51011m . (a) Calculate the average speed of Earth in its orbit (assumed to be circular) in meters per second. (b) What is this speed in miles per hour?

The CERN particle accelerator is circular with a circumference of 7.0 km. (a) What is the acceleration of the protons (m=1.671027kg)that move around the accelerator at 5of the speed of light? (The speed of light is v=3.00108m/s .) (b) What is the force on the protons?

Speed is a(n) ___ quantity. (2.2)

A block projected up a frictionless inclined plane with a speed of vo. The angle of incline θ. A) How far up the plane has it go?  B.) How long does it take to get there?  C.) What is its speed when it gets back to the bottom? Find the numerical answers for θ = 350 and  vo = 8.2 ft/s.

a frictionless plane is 10.0 m long and inclined at 31.0 degree a sled starts at the bottom with an initial speed of 5.40 m/s up to incline. when the sled reaches the point at which it momentarily stops, a second sled is released from the top of the incline with an initial speed v1. both sleds reach the bottom of the cline at the same time. A. determine the distance that the first sled traveled up the incline. ___________ m Determine the initial speed of the second sled _________ m/s

Stacked blocks and pulley Mass Ma lies on top of mass Mb, as shown. Assume Mb > Ma. The two blocks are pulled from rest by a massless rope passing over a pulley. The pulley is accelerated at rate A. Block Mb slides on the table without friction, but there is a constant friction force f between Ma and Mb due to their relative motion. Find the tension in the rope.
