Question

If u = 5 m /s , a = 12 m / s² , t = 3 s, then v = ? 20 m/s 63 m/s 41m/s 27 m/s

Answer 1

Answer:

u=5m/s a=12m/s^2 and t=3 sec, v=?

Explanation:

v=u +at(equation of motion Ist)

v=5 + (12×3)

v=5+36

v=41 m/s (0ption C)

Answer 2

Answer:

41 m/s

Explanation:

Solution

a = v - u/t

or, 12 = v-5/3

or, 36 = v - 5

or, 36+5 = v

or, 41 = v

Hence v = 41 m/s
