Question

a car is started to move from the rest and cover to kilometre distance producing and acceleration of 0.5 metre per second square find its final velocity how much does it take to cover the distance of 1.6 km​

Answer 1

Explanation:

initial velocity(u) = 0m/s

distance(s) = 1000m

acceleration(a) = 0.5m/s^2

final velocity = ?

using the 3rd equation

v^2 = u^2 + 2as

v^2 = 0 +2(0.5)(1000)

v^2 = 1000

v = $10\sqrt{10} = 31.62 m/s$
