The first spring has the stiffness -> 10 N/cm the second has the stiffness-> 2 N/cm

They're now put together that they are one whole spring.

calculate the spring stiffness of the newly created spring

Write a question about how changing temperature affects the gas inside the sports ball

Acoyote chasing a rabbit is moving 8.00 m/s due east at one moment and 8.80 m/s due south 4.25 s later. let the x axis point due east and the y axis point due north. find the direction of the coyote's average acceleration during that time.

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)
