A 151 kg crate is placed on an adjustable inclined plane. If the crate slides down the incline with an acceleration of 0.8 m/s2 when the incline angle is 31 degrees, what should the incline angle be for the crate to slide down the plane at constant speed ?
Bob pushes on a frictionless cart of mass 6.8 kg and the cart has an acceleration of
1.2 m/s2. If his friend Bill pushes twice as hard on an identical cart, what will be the
acceleration?
Your Answer:
Answer
A scale in the elevator’s floor measures the weight of the passengers, and it has the correct value when the elevator is not moving. The combined mass of the passengers is 572 kg.
The elevator is moving up at a constant speed of 3.2 m/s. What is the acceleration of the elevator for this part?
