Question

9. A car increases its speed
from 20 m/s to 50 m/s in 10 S,
then its acceleration is... .
O 2 m/s ^2
O 3 m/s ^2
O 5 m/s ^2
7 m/s ^2

10 . what is the average velocity of a car if it covers 60 km in 3 hours?

30 km / h
180 km /h
10 km /h
20 km /h
​

Answer 1

Answer:

acceleration is given by the change in velocity wrt to time.

so the total change in velocity is 30km/s.

acceleration is given by taking care of unit of the time and distance both

10×3600

30×1000

=
