A trolley is being up an incline plane by a man inside the trolley He applied a force of 500 N. If the mass of the man is 50 kg and trolley is 150 kg, then the acceleration of the trolley will be : (`g = 10 m//s^(2)`)

A

`5 m//s^(2)`

B

`1 m//s^(2)`

C

`1.5 m//s^(2)`

D

`2.5 m//s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`3T - 200 xx 10 xx (1)/(2) =200a`
`3 xx 500 -1000 = 200a`
`a = 2.5 m//s_(2)`
