Question

If a car with an initial velocity of 10 m/s accelerates at a rate of 50 m/s^2

for 3 s. What will be the final velocity? *

Answer 1

Given:

Initial velocity (u) = 10 m/s

Acceleration (a) = 50 m/s²

Time taken (t) = 3 s

To Find:

Final velocity (v)

Answer:

By using equation of motion, we get:

`\bf \longrightarrow v = u + at \\ \\ \rm \longrightarrow v = 10 + 50 * 3 \\ \\ \rm \longrightarrow v = 10 + 150 \\ \\ \rm \longrightarrow v = 160 \: m {s}^( - 1)`

`\therefore` Final velocity (v) = 160 m/s
