Question

If a force of 80 Newtons is applied to an object for 4 seconds, and the

object's mass is 10 kilograms, what is the change in velocity?
30 m/s.
32 m/s
40 m/s
35 m/s

Answer 1

The change in velocity is 32 m/s.

Step-by-step explanation:

To determine the change in velocity, we can use the equation:

Force = Mass × Acceleration

First, we need to calculate the acceleration using Newton's second law:

Acceleration = Force / Mass

Substituting the given values:

Acceleration = 80 N / 10 kg = 8 m/s2

Next, we can calculate the change in velocity using the equation:

Change in Velocity = Acceleration × Time

Substituting the values:

Change in Velocity = 8 m/s2 × 4 s = 32 m/s

Therefore, the change in velocity is 32 m/s.
