A car travels in a straight line for 3.7h at a constant speed of 63 km/h.

What is the acceleration?
Answer in m/s^2

constant speed? zero acceleration.

To find the acceleration, we need to use the formula:

Acceleration (a) = (Change in velocity) / (Change in time)

In this case, since the car is traveling at a constant speed, there is no change in velocity. Thus, the acceleration is 0 m/s^2.

A car traveling in a straight line has a velocity

of 6.03 m/s at some instant. After 6.89 s, its
velocity is 10.6 m/s.
What is its average acceleration in this time
interval?
Answer in units of m/s
