Answers

1
If the velocity of an object changes from 20 m/s to 5 m/s over 3 seconds,
the average acceleration is 15 m/s/s
the average acceleration is -15 m/s/s.
the average deceleration is 15 m/s/s
the average acceleration is 1/4 m/s/s.
2
If the velocity of an object changes from 50 m/s to 90 m/s over the course of 10 seconds,
the average acceleration will be 4 m/s/s
the average acceleration will be 140 m/s/s.
the average acceleration will be 4/10 m/s/s.
the average acceleration will be negative.
3
Displacement is
a vector.
a scalar.
4
Velocity is
change in displacement per unit of time.
change in speed per unit of time.
change in direction per unit of time.
5
If the vector direction and acceleration direction are opposite,
the object will stop accelerating.
the object is accelerating in a positive direction.
the object is decelerating.
the object 0 displacement.
