A stuntman drives a car with a mass of 1600 kg on a drawbridge. The car accelerates with a constant force of 8000 N. While he is driving, the
* drawbridge is raised to an incline of 30°. What is the car's new acceleration
on this incline, ignoring the force due to air resistance? (Recall that g= 9.8
m/s2)
Force accelerating car
Weight
A. -1.2 m/s2
B. 0.1 m/s2
h
O C. 2.5 m/s2
D. 1.3 m/s2

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
