Answer 1

Question :- A car travels with initial velocity of 30m/s for 20minutes with final velocity for 50m/s. How far does it travel?

Given : u = 30m/s t = 20min v = 50m/s

Solution :

To find the distance we need acceleration,

So,

a = (v-u)/t

= (50-30)/20

= 20/20

= 1 m/s²

Now,

s = ut+½at²

= (30*20) + (½*1*20*20)

= 600 + 200

= 800m

Hence, the car will travel 800m.
