Question

a bike acquires a velocity of 54 km per hour in 10 seconds just after the start. calculate the bike acceleration​

Answer 1

Explanation:

54 km/h = 15 m/s

a = (v-u)/t

a= (15 - 0)/10

a = 15/10

a = 1.5m/s²

Answer 2

bike acceleration​ is 1.5 m/s² if a bike acquires a velocity of 54 km per hour in 10 seconds just after the start.

Explanation:

velocity of 54 km per hour in 10 Secs just after start

before start velocity = 0  as it is at rest

Velocity after 10 sec  = 54 km /hr

= 54 * 1000 / 3600  m/s

= 30/2

= 15 m/s

V = U + at

V = 15 m/s

U = 0

a =  ?

t = 20 Sec

15   = 0  + a(10)

=> a = 15/10

=> a = 1.5

Bike Acceleration  is 1.5 m/s²
