a car starting from test accelerates at a rate of 2m/sec^2. find the average speed in the first ten seconds

Average speed in first ten seconds in 10 m/s

Step-by-step explanation:

We have equation of motion s = ut + 0.5 at²

Initial velocity, u = 0 m/s

Acceleration, a = 2 m/s²

Time, t = 10 s

Substituting

s = ut + 0.5 at²

s = 0 x 10 + 0.5 x 2 x 10²

s = 100 m

Distance traveled is 100 m

Time taken is 10 seconds

We have

Distance = Time x Average speed

100 = 10 x Average speed

Average speed = 10 m/s

Average speed in first ten seconds in 10 m/s
