When starting a foot race, a 70.0kg sprinter exerts an average force of 650 N backward on the ground for 0.800 s. How far does he travel? a) 1.48 m (b) 2.97m (c) 5.95 m (d) 11.9m

Which gives the kinetic energy of a descending yo-yo?

An advanced computer sends information to its various parts via infrared light pulses traveling through silicon fibers (n = 3.50). To acquire data from memory, the central processing unit sends a light-pulse request to the memory unit.

In what frame of reference would you be at rest while riding in a car?

Potential energy of an apple is 6j. the apple is 3.00m high. what is the mass of the apple?

How do mountins building and volcanos relate to plate motion at convergent boundaries

Suppose a person whose mass is m is being held up against the wall with a constant tangential velocity v greater than the minimum necessary. Find the magnitude of the frictional force between the person and the wall

A ball is being rolled by a normal push of 1000N. it is opposed by friction which has a force of 0.3kN and air resistance which has a force of 23N. Calculate the resultant force.

Consider a Young's two-slit experiment in which the wavelength of light is 37% smaller than the distance between the slits.
