a=50m/s^-2
v=100km/h
=100×5/18 m/s
=250/9m/s
v=u+at
250/9 = 0+ (50)(t)
250/9= 50t
5/9 s = t

Answer:
T = 5/9 sec
Explanation:
a car accelerates by 50m/s².it would attain a speed of 100k/h,form rest in
Final Velocity = 100 km/hr
1km = 1000m
1 hr = 3600 sec
100 km/hr = 100 * 1000 /3600 m/s
= 1000/36 m/s
= 250/9 m/s
a = 50 m/s²
U = 0 m/s (initial Velocity at Rest)
V = U + at
250/9 = 0 + 50*T
=> T = 5/9 sec
