Correct Significant Figures Feedback: Your answer 3214 N was either rounded significant figures than required for this part Learning Goal: To practice Problem-Solving Strategy 7.1 for interacting-objects problems. A 1260-kg car is pushing an out-of-gear 2160 -kg truck that has a dead battery. When the driver steps on the accelerator, the drive wheels of the car push horizontally against the ground with a force of 4600 N Assess The rolling friction of the car can be neglected, but the heavier truck has a rolling friction of 755 N including the "friction" of turning the truck's drivetrain. What is the magnitude of the force the car applies to the truck? Part D What is the acceleration ar of the truck? in meters per second squared to three significant figu View Available Hint(s) m/ aT = SubmitExplanation / Answer
Given,
Mc = 1260 kg ; Mt = 2160 kg ; Fp = 4600 N ; Ff = 755 N
The net force will be:
Fnet = Fp - ff
M a = 4600 - 755 = 3845 N
M = Mt + Mc
a = 3845/M = 3845/(2160 + 1260) = 1.12 m/s^2
Hence, a = 1.12 m/s^2
