Question

question 1 (1 point)
in which case do you think acceleration is involved?
o a the tru t 80kmph
o b the plane at 1000kmph
o c none of them

question 2 (1 point)
a change of velocity means that a body is
o a has constant velocity
o b accelerating

Explanation:

For Question 1, just stating the speed of a truck and a plane (constant speeds given) does not imply acceleration as acceleration is a change in velocity over time. For Question 2, by definition, a change in velocity means a body is accelerating.

Answer:

Question 1: c. none of them
Question 2: b. accelerating
