Question

an object starts from rest and attains a velocity of 54 km/h in 1 minute. Calculate distance travelled during this time???​

Answer 1

Answer:

450m

Explanation:

Speed = 54 km/hr = (54×5/18) m/s= 15m/s=v

u=0

t=60s

Using 1st equation of motion,

v=u+at

15=0+a60

a=15/60=1/4 m/s

Now using 3rd equation of motion,

2as=v^2-u^2

2×1/4 × s= 15^2 - 0

s/2 = 225

s = 450 m = 0.45km
