Question #948

A dragster and driver together have mass

888.7 kg . The dragster, starting from rest,

attains a speed of 25.4 m/s in 0.55 s .

Find the average acceleration of the drag-

ster during this time interval.

Answer in units of m/s2

888.7 kg . The dragster, starting from rest,

attains a speed of 25.4 m/s in 0.55 s .

Find the average acceleration of the drag-

ster during this time interval.

Answer in units of m/s2

Expert's answer

Fron the equation of the motion

v= v_{0}+at, v_{0} = 0;

we can find the average acceleration

a = v/t = 25.4/0.55 = 46.2 m/s^{2}^{}

v= v

we can find the average acceleration

a = v/t = 25.4/0.55 = 46.2 m/s
