9. A car starts from rest and moves along the X-axis with accerleration 5 m/s for
seconds. If it then continues with constant velocity, what distance will the car cov
in 12 seconds since it started from the rest?

10. Write the difference the between the acceleration and velocity​

Answer 1

Answer:

Hope it helps u...

Explanation:

5) p=mv

150=30v

v=50

10) The main difference between acceleration and velocity. Here are the basic definitions of acceleration and velocity. Acceleration - The rate of velocity Change over tym. Velocity - The rate of displacement of a moving object over tym..
