Practice on Speed, Velovity, and Acceleration

Question 1: A quantity used to measure how the velocity changes over time is called
Question 2: A school child throws a ball downward from rest and then realized that the ball covers a distance of 1.0 m in a time of 5.0 s.
Calcualte the ball's acceleration.
Question 3: A motorbike runs 10 meters in the first second from point A to point B, then runs 15 more meters from B to C in the next second, and finally, run for 20 meters from C to D in the last second. Calculate the acceleration of the motorbike.
Question 4: A motorbike starts from rest, and then goes through a contant acceleration and travels a distance of 1000 meters.
The motorbike reaches a final speed of 100 meters/second.
Calcualte the time it takes the motorbike to cover 1000 meters.
Question 5: Assume a boat traveling at constant speed
Question 6: A school child throws a ball downward from rest and then realized that the ball covers a distance of 2.0 m in a time of 4.0 s.
Calcualte the ball's average speed.
Question 7: Which two quantities will always have the same magnitude?
Question 8: Which of the following quantities relating to motion is not a vector?
Question 9: A car starts from rest and reaches 40 m/s in 10 seconds.
The average acceleration of the car is
