Question

A car start from rest and acquire the velocity of 54 km/hr in 2 seconds. Find the distance travelled by car assume motion of car is uniform
​

Answer 1

Answer:

15 m

Explanation:

Convert 54 kmph into m/s

54*5/18 = 15 m/s

Now:

v=u+at

v=at

v/t = a    ------ 1

Step 2:

S=ut+ 1/2*a*t

S= 1/2*a*t

(Substituting value of a in 1)

S = 1/2 * v/t * t

S=1/2 * v * t

S=1/2*15*2

S= 15 meters
