A green car with a mass of 900 kg is placed in the back of a yellow

Question

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.
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.

Answer 1

The car is held in place with a
chain at the top end of the lift, as pictured below.>>
This statement is too vague for physics.

Answer 2

a) T=mg sin 15
=(900 kg)(9.8 m/s^2)(sin 15)
= 2282.78 N, T<3000 N
Therefore, the chain will not snap.

b) i)T=mg sin 20
= (1500 kg)(9.8 m/s^2)(sin 20)
= 5027.69 N, T>3000 N
Therefore, the chain will snap.
ii) a= g sin20
= (9.8 m/s^2)(sin 20)
= 3.35 m/s^2

Answer 3

Thanks for asking this idk how to do this one either
