Question

The solution must contain an identification in words of the physical concept being applied (for example, conservation of momentum, kinematics, Coulomb’s Law, etc.)

The solution must contain a general algebraic form (i.e., with no numbers inserted from the problem information) of each basic equation being applied. Thank you

Rec. Inst. Name A green car with a mass of 900 kg is placed in the back of a yellow tow truck that has a pivot at one end. The car is held in place with a chain at the top end of the lift, as pictured below. The chain holding the car in place can withstand a maximum force of 3000 N. Rep: ID: Eq: Check: Neat: Total: Correct ans: YN 0 0.5 1 0 0.5 1 0 0.25 0.5 0 0.25 0.5 1 0.5 0 a) If the tow truck lifts its bed to an angle of θ- 15 , will the chain snap? Assume that the car is in neutral, so friction is negligible between the wheels of the car and the bed of the truck. Later, the same tow truck picks up a minivan with a mass of 1500 kg. When the truck lifts its bed to an angle of θ-20°, the chain holding the minivan breaks. b) With what acceleration does the minivan roll down the back of the truck? Assume that the minivan is in neutral, so friction is negligible between the wheels of the minivan and the bed of the truck.
