Question

Q-3 a scooter aquires a velocity of 36km\h in 10 seconds just after the start.calculate the acceleration of the scooter (economics class9th)

Answer 1

Answer:

Given :  

u (initial velocity) = 0 (rest)

v (final velocity) = 36 km/ hr = 36 × (1000/3600)

v = 36× 5/18 = 10 m/s. , t = 10s

From first equation of motion , v = u + at

10 = 0 + a ×10

10 = 10a

a = 10/10

a = 1 m/s²

acceleration of the scooter = 1 m/s²
