initial speed of car=20 km/hr = 5.55 m/s
final speed of the car= 60 km/hr= 16.667m/s
time taken=6 sec
Acceleration=(v-u)/t [v=final velocity ; u=initial velocity ; t=time taken ]
∴Acceleration=11.112 m/s²
NOTE:
# All the units should be of same order, hence we have to convert km/hr speed of car to m/s, since time given is in sec.
# To convert km/hr to m/s just multiply the given value of km/h with 5/18
final speed of the car= 60 km/hr= 16.667m/s
time taken=6 sec
Acceleration=(v-u)/t [v=final velocity ; u=initial velocity ; t=time taken ]
∴Acceleration=11.112 m/s²
