What is the impulse that a car with a mass of 6kg experiences when its velocity changes from 23m/s to 6m/s? what is the impulse that the wall creates when it applies a force of 29n over a period of 7s in a collision? a ball of clay with a mass of .1 kg hits the floor and comes to a stop. just before it hits the floor the velocity was -5.69m/s. if the collision took .64 s, how much force is the floor exert on the ball of clay?

Why can blue light and yellow light combine to produce white light? question 17 options: they are both primary colors of light. they absorb each other's wavelengths. because blue, yellow, and white are primary colors. they are complementary colors of light.

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
