Difficult

Angled Force with Friction

APPH12-CV0YS7

A $70\ kg$ crate is pushed across a rough floor by a $500\ N$ force exerted at $37^{\circ}$ below the horizontal, and the coefficient of kinetic friction between the crate and floor is $0.3$.

Which of the following is closest to the crate's acceleration?

A

$$1.4\ { m }/{ { s }^{ 2 } }$$

B

$$2.9\ { m }/{ { s }^{ 2 } }$$

C

$$4.0\ { m }/{ { s }^{ 2 } }$$

D

$$5.4\ { m }/{ { s }^{ 2 } }$$
