How many times will the body’s speed change if its impulse increases by 4 times.

To calculate the change in the speed of the specified body, we use the relation: k = Pk / Pn = m * Vk / (m * Vn) = Vk / Vn, from where we express: Vk = k * Vn.

Variables: k – increase in the momentum of the specified body (k = 4 p).

Calculation: Vk = k * Vn = 4Vn.

Answer: The speed of the indicated body will increase by 4 times.
