Question

Calculate the impulse for an object when it has mass of 15kg and a final velocity of 20m/s and an initial velocity of 1m/s.

Answer 1

To calculate the impulse, use the formula: Impulse = mass × change in velocity. For an object with a mass of 15kg, a final velocity of 20m/s, and an initial velocity of 1m/s, the impulse is 285 kg·m/s.

Step-by-step explanation:

To calculate the impulse, we can use the equation:

Impulse = mass × change in velocity

Given that the mass of the object is 15kg, the final velocity is 20m/s, and the initial velocity is 1m/s, we can plug in the values to calculate the impulse:

Impulse = 15kg × (20m/s - 1m/s) = 285 kg·m/s

So, the impulse for the object is 285 kg·m/s.
