Question

two cars x and y start of a race on a straight path with initial velocity of 8ms-1 and 5ms-1 respectively car x moves with a uniform acceleration of 1ms-2 and car y moves with uniform acceleration of 1.1 ms-2 if both the car reach the winning post together then length of the track is
​

Answer 1

Answer:

s=2.28km

Explanation:

u1=8m/s

u2=5m/s

a1=1m/s^2

a2=1.1m/s^2

s=ut+1/2at^2

8t+1/2t^2=5t+1.1/2t^2

t=60s

now,

s=2.28km
