Equations of motion (kinematic equations 2)

A boat travels 12.0 m while it reduces its velocity from 9.5 m/s to 5.5 m/s. What is the magnitude of the boat’s acceleration while it travels the 12.0 m?

• 1.3 m/s²
• 2.5 m/s²
• 3.0 m/s²
• 7.5 m/s²

What is velocity?

• the quickness of an object
• the location of an object
• acceleration
• speed in a specific direction

How far will a car move in 5 seconds if it started from rest and accelerates uniformly at 2.5 ms^-2?

• 12.5 m
• 125 m
• 6.25 m
• 31.25 m

A dog basks in the sun when he sees a squirrel and bolts after it. If the dog accelerates at +1.6 m/s², how far does he run in 3 seconds?

• 4.8 meters

• 45 meters

• 1.6 meters

• 7.2 meters

If a car is traveling forward at 15 m/s, how fast will it be going in 1.2 seconds if the acceleration is -10 m/s²?

• 27 m/s
• 3 m/s
• -27 m/s
• -3 m/s

An airplane accelerates down a runway at 4 m/s² for 24 s until is finally lifts off the ground. Determine the distance traveled before takeoff?

• 1152m

• 2304m

• 48m

• 1000m

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

An airplane accelerates down a runway at 4 m/s² for 24 s until is finally lifts off the ground. Determine the velocity just as it takes off?

• 48m/s

• 24m/s

• 96m/s

• 0m/s
