A10.0-kg box starts at rest and slides 3.5 m down a ramp inclined at an angle of 10° with the horizontal. if there is no friction between the ramp surface and crate, what is the velocity of the crate at the bottom of the ramp? (g = 9.8 m/s2) group of answer choices

Explanation:

As we know that box was initially at rest

so here work done by all forces on the box = change in its kinetic energy

so we will have

now we have

m = 10 kg

L = 3.5 m

so we will have

so final speed is given as

he kicked it 10 feet straight up into the air? i think this works.
