A block is placed on a parabolic shape ramp given by equation . If the coefficient of static friction is , then what is the maximum height above the ground at which the block can be placed without slipping?
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
The block will start slipping when the slope of the curve will be equal to tanθ where θ is angle of repose. The slope of the curve at any x will be, m=dydx=x10. Equating, μs=x10⇒0.5=x10⇒x=5 m Height at x=5 will be, h=x220=1.25 m
