Question

c


How long does it take to accelerate
a car from a speed of 50 km/h
to a speed of 100 km/h at an
acceleration of 1 m/s² ?​

Answer 1

Answer:

Given:

initial velocity,u=50km/h

=13.8m/s

final velocity,v= 100km/hr=

27.7m/s

acceleration= 1m/s^2

time - let time be t

V=U+AT

27.7= 13.8+1*T

T= 27.7-13.8/1

T= 13.9 sec
