Day 3 - Kinematics

Question 1

It is the change of position of an object that requires magnitude and direction.

Answer 1

Displacement

Question 2

It is the measurement of how far you travelled over a period of time. It is also known as the speed with direction.

Answer 2

Average Velocity

Question 3

The velocity at a specific instant of time or specific point along the path.

Answer 3

Instantaneous Velocity

Question 4

It is the rate at which velocity changes.

Answer 4

Acceleration

Question 5

The acceleration at a specific instant of time.

Answer 5

Instantaneous Acceleration

Question 6

An airplane accelerates down a runway at 3.20 m/s^2 for 32.8s until finally lifts off the ground. Determine the distance traveled before takeoff.

Answer 6

d = 1720m

Question 7

A car starts from the rest and accelerates uniformly over a time of 5.21 seconds for a distance of 110m. Determine the acceleration of the car.

Answer 7

a = 8.10 m/s/s

Question 8

Upton Chuck is riding the Giant Drop at Great America. If Upton free falls for 2.60 seconds, what will be his final velocity and how far will he fall?

Answer 8

d = 33.1m
Vf = 25.5 m/s

Question 9

A race car accelerates uniformly from 18.5m/s to 46.1m/s in 2.47s. Determine the acceleration of the car and the distance travelled.

Answer 9

a = 11.2 m/s/s
d = 79.8 m

Question 10

A bike accelerates uniformly from the rest to a speed of 7.10m/s over a distance of 35.4m. Determine the acceleration of the bike.

Answer 10

a = 0.712m/s/s
