A motorcycle can reach a speed of 60 mi/hr much faster than a minivan can

Newton's Second Law of motion

Explanation:

Newton's second law of motion states that 'the rate of change of the momentum of a body is directly proportional to, and in the same direction as, the net force acting on it.' This law applies to the given situation stating that 'a motorcycle can reach a speed of 60mph much faster than a minivan' as the smaller mass accelerates more quickly than the larger. This is because the van would require a more stopping distance as it would be difficult to decelerate due to the heavy mass. While for a motorcycle, it would be much easier to decelerate due to lesser mass. Thus, Newton's second law applies here.

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

a is the best answer your welcome
