Question

racing car has a uniform acceleration of 5 metre per second square what distance will it cover in 20 seconds after starting from rest

Answer 1

s=ut+1/2at²
s=0(20)+1/2(5)(20)²
s=0+1/2(5)(400)
s=5(200)
s=1000m

Answer 2

Hello!!

According to the given data,

a car is travelling in uniform acceleration. it means that it will travel equal distances in equal intervals of time.

let's apply a formula for this, to know the answer.

You have asked the distance.

so the formula for distance (s) is :-

s=ut+1/2at^2
s=(0)+1/2(5)(20)^2
s=1/2 (5) (400)
s=(5) (200)
s=1000m/s

Hence the distance covered in 20seconds is 1000m/s.

Hope it helps!!
