Two crates, of mass m1m1m_1 = 59kg and m2= 116 kg, are in contact and at rest on a horizontal surface. Force F= 690 NN is exerted on the 59-kg crate. The coefficient of kinetic friction is 0.18.

a- Determine the acceleration of the system.Express your answer to two significant figures and include the appropriate units.

b- Determine the magnitude of the force that each crate exerts on the other.Express your answer to two significant figures and include the appropriate units.

c-If the crates are reversed, determine the acceleration of the system.Express your answer to two significant figures and include the appropriate units.

d-If the crates are reversed, determine the magnitude of the force that each crate exerts on the other.Express your answer to two significant figures and include the appropriate units.
