Kinematics and Acceleration Problems

An Indy 500 race car's velocity increases from +4.0 m/s to +36 m/s over a 4.0s time interval, what is the average acceleration?

• 12.34 m/s

• 8.0 m/s²

• 8.0 m/s

• 69 m/s²

An airplane accelerates down a runway at 3.20 m/s² for 32.8 s until it finally lifts off the ground. Determine the distance traveled before takeoff.

• 1720 m

• 420 m

• 5.23 m

• 79 n

It was once recorded that a Jaguar left skid marks that were 290 m in length. Assuming that the Jaguar skidded to a stop with a constant acceleration of -3.90 m/s2, determine the speed of the Jaguar before it began to skid.

• 12.48 m/s

• 28 m/s

• 44.4 m/s

• 47.6 m/s

What is happening during point A to B?

• not moving

• increasing speed at a constant rate

• moving at a constant speed

• moving at 10 m/s² acceleration

What is happening during point C to D?

• not moving

• increasing speed at a constant rate

• moving at a constant speed

• moving at 0 m/s² acceleration

What is the graph showing?

• Slowing down moving toward start

• Speeding up moving toward start

• Slowing down moving away from start

• Speed up moving away from start

What is the graph showing?

• Speeding up moving away from start

• Speeding up moving towards start

• Slowing down moving towards start

• Slowing down moving away from start

What is the graph showing?

• Constant speed towards start

• Constant speed away from start

• Acceleration away from start

• Acceleration towards start

Which graph represents the greatest acceleration?

• A
• B
• C
• D

Along line segment B, the object is:

• Not moving

• Moving at a constant velocity

• Changing direction

• Experiencing acceleration
