A sports car accelerates from rest to 95 km/h in 4.3 sec . we have to find average acceleration in m/s².
first of all, we should change 95 km/h in m/s
so, 95 km/h = 95 × 1000/3600 m/s
= 95 × 5/18 = 475/18 m/s
≈ 26.4 m/s
we know, acceleration is the rate of change of velocity. or you can say that acceleration is change in velocity per unit time.
so, Acceleration = (final velocity- initial velocity)/time taken
here, initial velocity= 0
final velocity = 26.4 m/s
time taken = 4.3 sec
now, Acceleration = 26.4/4.3 ≈ 6.14 m/s²
first of all, we should change 95 km/h in m/s
so, 95 km/h = 95 × 1000/3600 m/s
= 95 × 5/18 = 475/18 m/s
