A person in a wheelchair is moving up a ramp at constant speed.Their total weight is `900N`. The ramp makes an angle of `37^(@)` with the horizontal. Calculate the component of its weight parallel and perpendicular to ramp.

A

`W_(||)=54N`, `W_(_|_)=72N`

B

`W_(||)=720N`, `W_(_|_)=540N`

C

`W_(||)=540N`, `W_(_|_)=720N`

D

`W_(||)=0N`, `W_(_|_)=720N`

Text Solution

Verified by Experts

The correct Answer is:
C
Component of weight parallel to ramp
`W_(||)=900 sin 37^(@)=540N`
Component of weight perpendicular to ramp
`W_(_|_)=900cos37^(@)=720N`
