500 kg . 0.10 N
500 kg / 0.10 N
500 kg + 0.10 N

The diagram shows a homemade car being pushed with a force of 25 N. The force causes the car to move at a constant speed of 3 m/s2. What will happen if the force is changed to 35 N?
The car will move at a constant speed of 13 m/s.
The speed of the car will not change.
The speed of the car will increase.
The speed of the car will decrease to 1 m/s.
Some students measure the acceleration of a wheel cart being acted on by varying forces. The students record their data in the table shown. According to the data table, how much force is acting on the cart when the students measure an acceleration of 2.6 m/s2.
13 N
7 N
8 N
12 N
The diagram below shows a boat moving north in a river at 3 m/s while the current in the river moves south at 1 m/s. How will the boat be affected if it enters a part of the river where the current is moving south at 2 m/s?
The boat will move slower.
The boat will move faster.
The boat will stop.
The boat will move to the west.
A meteor is moving 468 km per minute traveling in a south-to-north direction passed near Earth in 2013. Because the meteor was only 45 m wide and was 27,700 km above Earth's surface, it was not visible without the aid of a telescope. Which statement describes the meteor's motion?

It's acceleration was 468 km/s2.
It's speed was 468 km/s northward.
Its acceleration was 7.8 km/s2.
