. An 8.70-kg block slides with an initial speed of 1.66 m/s up a ramp inclined at an angle of 27.4 degrees with the horizontal. The coefficient of friction mu between the block and the ramp is 0.62. Find the distance the block slides before coming to rest.

Bone-strengthening physical activity done increases bone-mineral content and bone density in youth.

Polly is pushing a box across the floor with a force of 30 n. the force of gravity is –8 n, and the normal force is 8 n. which value could describe the force of friction if polly could not move the box?

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy
