Consider hitting a baseball with a bat. Which scenario is true?
The force that the baseball exerts on the bat and the force that the bat exerts on the baseball are the same magnitude.
Which has the greater acceleration: the bat or the ball?
The ball because it has a smaller mass than the bat.
Two identical small cars (car A & car B) have a head-on collision. Which scenario is true?
The force that car A exerts on car B and the force that car B exerts on car A are the same magnitude.
Consider question 3. Which has the greater acceleration: car A or car B?
Both Cars A and B have the same acceleration magnitude
A large truck and a small car have a head-on collision. Which scenario is true?
The force that the truck exerts on the car and the force that the car exerts on the truck are the same magnitude.
Consider question 5. Which has the greater acceleration: the truck or the car?
The car has the greater acceleration because it has the smaller mass.
Ryan is driving his car to band practice. His speed is 55 mph. Splat! A bug smashes against the windshield, and bug "guts" are everywhere. Gross! Which scenario is true?
The force that the windshield exerts on the bug and the force that the bug exerts on the windshield are the same magnitude.
Consider question 7. Which has the greater acceleration: the bug or the windshield?
The bug has the greater acceleration because it has the smaller mass.
Jenny and Betty are having a great time at Busch Gardens riding the Ubanga Banga bumper cars. Jenny, who is traveling southward in her bumper car, aims her car toward Betty, who is traveling northward in her bumper car. The cars collide and briefly come to a stop.
What is the direction of the force exerted on Jenny's car during the collision?
The direction of Jenny's car was going northwards.
Jenny and Betty are having a great time at Busch Gardens riding the Ubanga Banga bumper cars. Jenny, who is traveling southward in her bumper car, aims her car toward Betty, who is traveling northward in her bumper car. The cars collide and briefly come to a stop.
What can you say about the magnitude of the force that Jenny's car exerts on Betty's car versus the magnitude of the force that Betty's car exerts on Jenny's car?
The magnitude between the two are equal.
Jenny and Betty are having a great time at Busch Gardens riding the Ubanga Banga bumper cars. Jenny, who is traveling southward in her bumper car, aims her car toward Betty, who is traveling northward in her bumper car. The cars collide and briefly come to a stop.
What is the direction of the acceleration of Jenny's car during the collision?
The acceleration of Jenny's car during the collision is southwards.
