Question

If it takes 25 N to slide the box up the ramp how much work will it take to slide the box top?​

Answer 1

Answer:

625J

Explanation:

Inclined plane is tool, which benefits us in force.

Inclined plane gives us benefit in force times the length of incline divided by the heigh of ramp.

So, F₂/F₁=l/h

F₁=25N

F₂/25=l/h

F₂=25l/h=125N

Work is Fh

W=125*5=625J

Hope it helps!

Answer 2

The work required to slide the box to the top of the ramp is 500 J

Given

Force to slide the box up the ramp = 25 N

Distance to the top of the ramp = 20 m

To Find

Work required to slide the box to the top

Solution

The formula for calculating work is given by $W = F * d* Cos$Ф where

$W$ is the work required

$F$ is the Force applied = 25 N

$d$ is the displacement, which is the distance of the ramp = 20 m

Ф is the angle of the force applied to the displacement which in this case is 0°

Substituting the values, the equation becomes,

$W = 25 * 20 * Cos$0° = $25 * 20 * 1$ = 500 Nm = 500 J

Hence, the work required to slide the box to the top of the ramp is 500 J
