8. Carol, who weighs 60 kg, is driving her car at a speed of 25 m/s. She sees a dog crossing the road and so she steps
on the brake to avoid hitting it. Her seatbelt brings her body to a stop in 0.40 s.
a. What average force does the seatbelt exert on her?
b. If she is not strapped to her seatbelt, and the windshield stops her head in 0.001 s, what average force would the
windshield exert on her?
A large semi truck has a mass of 35,000 kg. It collides head on with a car that has a mass of 1000 kg. The car’s initial velocity is 10 m/s and the truck’s initial velocity is 5 m/s in the opposite direction. Which of the following can you say about the forces and velocities of the two vehicles?
a. The force that the truck makes on the car is equal to the force the car makes on the truck so the car’s velocity changes by the same amount that the truck’s velocity does.
b. The mass of the truck is so much larger than the car that the force of the truck on the car is much greater than the force the car puts on the truck and the car velocity after the collision is in the opposite direction.
c. The force that the truck makes on the car is much larger than the force the car makes on the truck so the car’s velocity changes much more than the truck’s does.
d. The force that the truck makes on the car is equal to the force the car makes on the truck but the mass of the truck is much…
Q2. A fisherman in a boat catches a great white shark with a harpoon. The shark
struggles for a while and then becomes limp when at a distance of 300 m from the boat.
The fisherman pulls the shark by the rope attached to the harpoon. During this
operation, the boat (initially at rest) moves 45 m in the direction of the shark. The mass of
the boat is 5400 kg. What is the mass of the shark? Pretend that the water exerts no
friction. (mshark = 953 kg)

- (a) What is the strength of the weak nuclear force relative to the strong nuclear force? (b) What is the strength of the weak nuclear force relative to the electromagnetic force? Since the weak nuclear force acts at only very short distances, such as inside nuclei, where the strong and electromagnetic forces also act, it might seem surprising that we have any knowledge of it at all. We have such knowledge because the weak nuclear force is responsible for beta decay, a type of nuclear decay not explained by other forces.arrow_forwardA hockey stick pushes a 0.160-kg puck with constant force across the frictionless surface of an ice rink.
