Multiple Choice

What can we find knowing that the displacement was 45 meters and the event took 7.8 seconds?

1

the final velocity is 5.77 m/s

2

the acceleration is 5.77 m/s/s

3

the average velocity is 5.77 m/s

4

the initial velocity is 5.77 m/s

How can we find the acceleration from this information?

1

it's the same, 11.5

2

take the final velocity and divide it by 2

3

take the final velocity and divide it by the time

Multiple Choice

Knowing the net force, the time applied, and the mass of the object, what can we find?

1

Acceleration: F = ma

2

Velocity: F = vt
