A ball whose mass is 0.4 kg hits the floor with a speed of 8 m/s and rebounds upward with a speed of 6 m/s. Collapse question part Part 1 (a) If the ball was in contact with the floor for 0.5 ms (0.5 × 10-3 s), what was the average magnitude of the force exerted on the ball by the floor?

The  the average magnitude of the force exerted on the ball by the floor N

Explanation:

Given:

Mass of ball kg

Initial speed

Rebound speed

Contact time interval sec

For finding the average magnitude of the force on the ball by the floor is given by,

Here

    N

Therefore, the  the average magnitude of the force exerted on the ball by the floor N

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
