Question

4. An object is moving with an initial velocity of 9 m/s. It accelerates at a rate of 1.5

m/s over a distance of 20 m. What is its new velocity?

Answer 1

11.87 ms⁻¹

Step-by-step explanation:

You can use the kinematic equation

v² = u² + 2as

Where v = final velocity

u = initial velocity

a = acceleration

s = displacement

v² = 9² + 2×1.5×20

So you get v = 11.87 ms⁻¹
