A dog is standing in the bed of a pickup truck. The truck bed is coated with ice, causing the force of trict between the dog and the truck to be zero. The truck is initially at rest, and then accelerates to the right, along a flat road. As seen from a stationary observer (watching the truck move to the right), the dog a. moves to the right at the same rate as the truck, so it doesn't slide. b. does not move left or right, but the back of the truck moves towards the dog. C. moves to the right, but not as quickly as the truck is moving to the right, causing it to slid towards the back of the truck. d. moves to the left, as the truck moves to the right, causing the dog to slide towards the b the truck. Reasoning: Vo : Truck Uf ked frictionless turns 1/2 ice bed wheels turned right location dog Newtons third Law: every action has equal mout of reaction in a system X Which of the following best explains how a rocket takes off? in this case the dog left and the truck a The rocket forces the exhaust gases down, and the hot gases push up on the rocket. The two forces a Newton's third-law pair. The rocket accelerates upward because the force of the exhaust gases or b. rocket is greater than the rocket force on the exhaust gases. 1 2 The rocket forces the exhaust gases down, and the hot gases push up on the rocket. The two forces a Newton's second-law pair. The rocket accelerates upward because the force of the exhaust gases the rocket is greater than the rocket force on the exhaust gases. C. The rocket forces the exhaust gases down, and the hot gases push up on the rocket. The two forces a Newton's third-law pair. The rocket accelerates upward because the force of the exhaust gases on d. rocket is greater than the force of gravity on the rocket. The rocket forces the exhaust gases down, and the hot gases push up on the rocket. The two forces a Newton's second-law pair. The rocket accelerates upward because the force of the exhaust gases the rocket is greater than the force of gravity on the rocket. Reasoning: Fexhaust Fexh > fa The rockets exhaust has to be greater than Fo in order to accelerate upwards
