Force, Mass, and Acceleration Practice Problems
Name_____Per. _____ Force, Mass, and Acceleration Practice Problems Formulas: Fnet = ma (net Force = mass times Acceleration ) a = v ( Acceleration = change in velocity divided by change in time) t F v Units: Force: Newtons (N) Acceleration : m/sec/sec or m/sec2 velocity: m/sec Conversions: 1 kg = 1000 g m a a t 1 kg weighs ~ 10 N on Earth 1 N = 1 kg-m/sec2 Problems : 1. Two cars accelerate at 2 m/sec2. Car A has a mass of 750 kg, while Car B has a mass of 1000 kg. What forces are required to accelerate each car? If you are concerned with the price of gas, which car would you rather drive and why? 2. A 500 kg rocket can accelerate from rest to a speed of 600 m/sec in 2 seconds. 2a. What is the Acceleration of the rocket ? 2b. How much force is required to accelerate it?
5. A rocket in space has a mass of 5000 kg, and is propelled by a rocket motor with 900,000 N of thrust, which burns for 4 seconds. 5a. What is the rocket’s acceleration? 5b. If the rocket starts at rest, how fast is the rocket going after the 4 second burn? 6. A 2 kg block is dragged across a table top at a constant velocity by means of a ...
