Question

A car starting from rest attains a velocity of 90 km/hr in 10 second,Now, calculate acceleration as well as distance covered by the car​

Answer 1

Answer:

I have it is in pic please check If it Is true then thanks me and mark as brainiliest

Answer 2

Explanation:

Car at rest so initial velocity u = 0km/hr

Attains a velocity,so final velocity v = 90km/hr

t = 10s = 1/6 hr

v = u+at

=> 90 = 0 +a×(1/6)

=> a = 90/1/6 = 540km/hr²

v²-u² = 2as

=> 90²-0 = 2×540×s

=> s = 8100/540=15 km
