Answer 2

Correct Question:-

A car accelerates for 6 Sec. the velocity of the car increase from 15m/s until the velocity is 28 m/s​.

Solution:-

Given,

• Car accelerates for 6sec and increase from 15m/s to 28m/s.

We can find the acceleration by using the first equation of motion:-

u = 15m/s ; v = 28m/s ; t = 6sec ; a = ?

➣ v = u + at

➣ 28 = 15 + 6a

➣ 28 - 15 = 6a

➣ 13 = 6a

➣ a = 13/6

➣ a = 2.16m/s²

We can find the distance by using the third equation of motion:-

➣ s = ut + 1/2 at²

➣ s = 15(6) + 1/2 * 2.16 * 6 * 6

➣ s = 90 + 2.16 * 6 * 3

➣ s = 90 + 38.88

➣ s = 128.88m
