Multiple Choice

A car is traveling to the right with a speed of 29​​m/s when the rider slams on the accelerator to pass another car. The car passes in 110 m with constant acceleration and reaches a speed of 34m/s. We want to find the acceleration of the car as it sped up. What equation should you choose?

• vf=vi+at

• x=vit+1/2at²

• vf²=vi²+2aX

• x=((vf+vi)/2)t

Multiple Choice

An object with an initial velocity of 3.50 m/s moves east along a straight and level path. The object then undergoes a constant acceleration of 1.80 m/s² east for a period of 5.00 s. How far does the object move while it is accelerating?

• 6.30 m

• 17.5 m

• 27.2 m

• 40.0 m

Multiple Choice

What statement is true?

• Mass never changes. Weight does.

• Weight never changes. Mass does.

• Both mass and weight change because they are affected by gravity.

• Neither mass nor weight change. They are always the same.
