2. Luis starts his car from rest at a stoplight. As soon as the light turns green, he steps on the gas and the car accelerates at a constant rate of 4.0 m/s². After6.0 seconds, he looks at the road ahead and wonders how far he has already traveled.

3. A car is moving with an initial velocity of 10 m/s and accelerates at 2 m/s²for 5 seconds. What is its final velocity?

4. A tricycle is parked in a terminal. Suddenly, it accelerated at 2m/s2 for 5s.How far did the tricycle move?

5. A car travels with a constant acceleration of 2 m/s2 for 8 s. If its initial velocity was 5 m/s, what is its final velocity?

6. A car accelerates from rest to 60 mph (26.8 m/s) in 8 seconds. What is its average acceleration?

7. You are driving 100 m behind a car that is moving at a constant velocity of 60 kph. From that distance (100 m behind) how much should you accelerate to overtake the other car within 20 s, if you are cruising at 30 kph?

A ball is dropped from the top of a 78.4-meter-tall building.

a. How long does it take to reach the ground?

A ball is dropped from the top of a 78.4-meter-tall building.

b. What is its velocity just before hitting the ground?

Assume no air resistance and use g = 9.8 m/s².
