Day 4 STAAR Review

Deep Space 1 was a spacecraft powered by an engine that gave off xenon particles to change velocity. It had a mass of 500 kg. Which expression can be used to find the spacecraft's acceleration if its engine created a net force of 0.10N?

Two students are working together to build a birdhouse. Student 1 applies a force of 10 N to a wooden board in order to slide it across the table to Student 2.

If the force of friction resisting the student's push is 4N, what is the net force acting on the board?

A basketball with a mass of 0.60 kg is accelerated with a force of 10.8 N. If resisting forces are ignored, what is the acceleration of the basketball to the nearest m/s²?

A student used a video camera to record another student dropping a marble through the water in a graduated cylinder. The students watched the video in slow motion and made the observations shown below.

During which part or parts of the marble's fall did the marble experience unbalanced forces?

A student graphed the position of a cart during a 7-second interval.

Which statement describes the cart?

Which of the following best describes the velocity of an object?
