You are trying to push your stalled car. Although you apply a horizontal force of 400 N to the car, it doesn't budge, and neither do you. What force(s) must also have a magnitude of 400 N?

The friction force exerted by the road on you

The force exerted by the car on you

The friction force exerted by the car on the road

The normal force exerted by the road on you.

Matt is able to move the large truck because

the ground exerts a greater friction force on Matt than it does on the truck.

the truck offers no resistance because its brakes are off.

he is heavier in some respects than the truck.

he exerts a greater force on the truck than the truck exerts back on him.

A golf ball is hit with a golf club. While the ball flies through the air, which forces act on the ball?

The force of gravity acting on the ball.

The force of the golf club acting on the ball.

The force of the ball moving forward through the air.

Suppose an object is accelerated by a force of 100 N. Suddenly a second force of 100 N in the opposite direction is exerted on the object, so that the forces cancel. The object

continues at the velocity it had before the second force was applied.

is brought to rest and then accelerates in the direction of the second force.

You are pushing a heavy box across a rough floor. When you are initially pushing the box and it is accelerating,

the force you exert on the box is equal to the force of the box pushing back on you.

you exert a force on the box, but the box does not exert a force on you.

the force that the box exerts on you is greater than the force you exert on the box.

the box is so heavy it exerts a force on you, but you do not exert a force on the box.

the force you exert on the box is greater than the force of the box pushing back on you

A truck is traveling horizontally to the right. When the truck starts to slow down, the crate on the (friction less) truck bed starts to slide. In what direction could the net force be on the crate?

No direction. The net force is zero.

Straight down (because of gravity) .

The normal force on an extreme skier descending a very steep slope can be zero if:Check all that apply.

he leaves the slope (no longer touches the snow).

the slope is greater than 75 ∘

When a skier skis down a hill, the normal force exerted on the skier by the hill is:

less than the weight of the skier.

greater than the weight of the skier

equal to the weight of the skier.
