Answer 1

Answer #1

Distance covered before applying brakes, d1 = 30 x 0.35 = 10.5 m

To calculate distance covered after applying brakes, we will use kinematic equation,

V^2 = u^2 + 2as

0 = 30^2 - 2(8 x d2)

Distance, d2 = 56.25 m

So, total distance is 56.25 + 10.5 = 66.75 m

B) total time= 0.35+ 30/8= 4.1 s

Plz post other problems seperately..

Comment in case any doubt.. Goodluck
