Answer :
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
[tex]a=\dfrac{P}{m}[/tex]
[tex]a=\dfrac{181\ N}{68\ kg}[/tex]
[tex]a=2.67\ m/s^2[/tex]
(c) P = 352 N
[tex]a=\dfrac{P}{m}[/tex]
[tex]a=\dfrac{352\ N}{68\ kg}[/tex]
[tex]a=5.17\ m/s^2[/tex]
Hence, this is the required solution.
