Given the following data for a fire extinguisher-toy wagon rocket experiment, calculate the average exhaust velocity of the gases expelled from the extinguisher. Starting from rest, the final velocity is 10.0 m/s. The total mass is initially 75.0 kg and is 70.0 kg after the extinguisher is fired.
Step-by-step solution In this problem we have to calculate the exhaust velocity of the gases expelled from the fire extinguisher-toy wagon rocket experiment. Step 1 of 2 The expression to find the final velocity is of wagon rocket is, Here, is exhaust velocity, is initial mass, is remaining mass, is final velocity and is initial velocity of the wagon rocket.
