6.3 Calculating Acceleration

 $a=\frac{\Delta\upsilon}{t}$  

An object at rest begins to move to a final speed of 20 m/s in 5 seconds. Calculate the object's acceleration.

 $t=\frac{\Delta v}{a}$  

A train travels at a constant acceleration of 6 m/s2, starting from standstill at a station and traveling along a straight track. How long does it take the train to reach 72 m/s?

Mark slams on the brakes after traveling 25 m/s. It takes him 3 seconds to come to a complete stop. What is his acceleration?

How much time did it take Matthew to slow down to a complete stop, after traveling at 30 m/s. His acceleration is -12 m/s²

If Anthony was running for 300 s after starting at rest, what was his final velocity if he had an acceleration of 0.05 m/s²

Mars’ gravitational force is less than that of Earth’s . If an astronaut drops a hammer and its speed increases from 0 to 15 m/s in 4.04 s, what is the acceleration due to gravity on Mars?

Georgia is jogging with a velocity of +4 m/s when she accelerates at +2 m/s² for 3 seconds. How fast is Georgia running now?

Pete is driving down 7th street. He drives 150 meters in 18 seconds. Assuming he does not speed up or slow down, what is his speed in meters per second?
