A 60 kg platform has been placed on a rough incline having inclination `theta = 37^(@)`. The coefficient of friction between the platform and the incline is `mu = 0.5`. A 40 kg man is running down on the platform so as to keep the platform stationary. What is the acceleration of the man? It is known that the man cannot manage to go beyond an acceleration of `7m//s^(2).["sin"37^(@) = (3)/(5)]`

Text Solution

Verified by Experts

The correct Answer is:
`5m//s^(2) le a le 7m//s^(2)`
