3. A 15 kg box slides down a frictionless ramp of 25 degrees. What is its acceleration?(adsbygoogle = window.adsbygoogle || []).push({});

m/s/s

What is the normal force of a 35 kg box sitting on a slope of 14 degrees? (assume the box is not moving).

N

A 45 kg box is sliding at a constant speed down a ramp of 28 degrees.

What is the frictional force on the box?

What is the coefficient of sliding friction?

After an initial push, a box goes up a frictionless incline of 20 degrees.

What is its rate of deceleration?

m/s/s

A 75 kg skier starts at the top of a 15 m incline at an angle of 25 degrees.

Assuming the coefficient of friction is .15, what is his acceleration?).

m/s/s

What is his speed at the bottom of the hill?

m/s

can someone do those for me just so i can figure out the logic like with the equations id ont get it at all thanks
