a mover uses a ramp to pull a 1000 newton caart up to the floor of his truck (0.8 meters high). If it takes a force of 200 Newtons to pull the cart what is the length of the ramp. FOR 50 POINTS

Respuesta :

I'm pretty sure it's 5 meters.
Ramp height: .8 meters.
Weight of cart: 1,000.
Force it takes: 200.
1,000/200.
=5
I hope it's right.
Tell me if it's not.

The length of the ramp is 4m.

Data;

  • weight of the cart = 1000N
  • distance which the cart moved = 0.8m
  • applied force = 200N

Length of the Ramp

To calculate the length of the ramp, let's us know the work done by gravity.

[tex]W= mgh\\w = 1000 * 0.8\\w = 800J[/tex]

The work done by gravity is 800J.

The length of the inclined ramp is given as

[tex]W = FL\\[/tex]

F = applied force

L = length of the ramp

[tex]W = FL\\800 = 200L\\L = \frac{800}{200}\\ L = 4m[/tex]

The length of the ramp is 4m.
