Peter throws a snowball at his car parked in the driveway. the snowball disintegrates as it hits the car. by newton’s third law, you know that both the car and the snowball exert a force on each other. what can you say about the magnitude of the forces exerted by the snowball and the car? . a. the force exerted by the car is more than the force exerted b y the snowballl.. b. the force exerted by the car is less than the force exerted by the snowball. c. the force exerted by the car is equal to the force exerted by the snowball. d. the force exerted by the car is zero.

C. The force exerted by the car is equal to the force exerted by the snowball.

Explanation:

Newton's third law of motion states that:

" When an object A exerts a force on object B, then object B exerts an equal and opposite force on object B". These two forces are called action and reaction, and the law states that the two forces are equal in magnitude, and opposite in direction.

In this problem, we are considering the force exerted by snowball on the car: we can say that this is the action force. Therefore, the force exerted by the car on the snowball is the reaction. Newton's third law states that the two forces are equal in magnitude: therefore, the only correct option can be

C. The force exerted by the car is equal to the force exerted by the snowball. .

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
