746 joules per second = 746 watts = 1 horsepower

340 joules per second = 340 watts = (340/746) = 0.456 horsepower

Power is a RATE or a SPEED of doing work.

How long you do it doesn't matter.

Just like 30 miles per hour doesn't change whether you do it for an hour or for 10 minutes.

Answer:

g= 1.8 m/s²

Explanation:

From conservation of energy we know:

$mgh=\frac{1}{2}mv^2$

Solving for g with h being the height of the ramp with angle ∅ and length L:

(1) $g=\frac{v^2}{2h}=\frac{v^2}{2Lsin\theta}$

The velocity v at the bottom of the ramp for a constant acceleration a in a time t is given by:

(2) $v=at=gsin\theta t$

Plugging equation 2 in to equation 1:

(3) $g=\frac{2L}{sin\theta t^2}$
