Question

a car travelling at 9 metre per second accelerated attains a speed of 87 metre per second in 5 seconds calculate the acceleration and the acceleration and the distance covered in second​

Answer 1

Explanation:

u = 9 m/s

v = 87 m/s

t = 5 sec

a = v-u

t

= 87-9

5

= 78 ÷ 5

= 15.6 m/s²

s = ut +½at²

= 9×5 + ½ × 15.6 × 5²

= 45 + 195

= 240 m
