Question

a racing car accelerates from rest to 4 m/s in 5 s. Calculate the distance travelled by the car. ​

Answer 1

Answer:

The distance travelled by the car is=10 m

Explanation:

Distance travelled (S)=?

From the equation, s=ut+1/2at²

Since, it accelerates from rest,

u=0,v=4m/s,t=5 sec

a=(v-u)/t

a=4/5m/s²

By substituting the above values.We get,

s=0*t+1/2*4/5*5²

s=1/2*4/5*25

s=10 m
