Question

If a car that travels with a velocity of 50 m/s suddenly accelerates to 5 m/s2 within 4 s, then what is its final velocity?

Answer 1

Answer:

Final velocity is 70m/s

Explanation:

Initial Velocity (u) = 50m/s

Acceleration (a) = 5m/s^2

Time (t) = 4s

Final Velocity (v) = ?

Solution :

Under the equation,

v = u + at

v = 50 + 5(4)

v = 50 + 20

v = 70 m/s

Therefore the velocity will be 70m/s
