Question

The 68-kg crate is stationary when the force P is applied. Determine the resulting acceleration of the crate if (a) P = 0, (b) P = 181 N, and (c) P = 352 N. The acceleration is positive if up the slope, negative if down the slope.

Answer 1

Step-by-step explanation:

Mass of the crate, m = 68 kg

We need to find the resulting acceleration if :

(a) Force, P = 0

P = m a

⇒ a = 0

(b) P = 181 N

`a=(P)/(m)`

`a=(181\ N)/(68\ kg)`

`a=2.67\ m/s^2`

(c) P = 352 N

`a=(P)/(m)`

`a=(352\ N)/(68\ kg)`

`a=5.17\ m/s^2`

Hence, this is the required solution.
