This test covers momentum, impulse, conservation of momentum, elastic collisions, inelastic collisions, perfectly inelastic collisions, 2-D collisions, and center-of-mass, with some problems requiring a knowledge of basic calculus. 1.
12) An object has an impulse of 150 N s applied to it. If the force was applied for 10s, what was the size of the force? 13) A 20 kg object accelerates from rest to a speed of 25 m/s. a) What was the initial momentum of the object? b) What was the final momentum of the object? c) What was the change in momentum? d) What was the impulse?
Momentum and Impulse Practice Problems Physics Academic Classroom Practice 1. A 1300 kg race car is traveling at 80 m/s while a 15,000 kg truck is traveling at 20 m/s. Which has the greater momentum? 2. A 300 kg snowmobile is traveling at 30 m/s. How fast would a 200 kg snowmobile need to travel to have the same momentum? 3.
This document contains a 21-question multiple choice practice test on momentum and impulse for an AP Physics 1 class. The questions cover topics such as momentum changes during collisions, conservation of momentum, impulse, and calculating momentum and speed changes.
(a) Find the momentum of the ball of dough at its maximum height. (b) Find the momentum of the ball of dough halfway up to its maximum height on the way up. 4) A batter hits a ball with a net force of 1220 N opposite to the direction of the ball’s initial momentum. The force acts on the ball for 9.0 x 10-3 seconds during the hit.
PRACTICE: MOMENTUM AND IMPULSE Objective: Use the impulse-momentum theorem to solve for an unknown variable. 1. An official major league baseball has a mass of 0.14 kg. A pitcher throws a 40 m/s fastball which is hit by the batter straight back up the middle at a speed of 46 m/s. a. What is the impulse of the ball during the collision with the bat?
9.1 Momentum and Impulse 1. The momentum of a 3000 kg truck is 6.36 × 104kg·m/s. At what speed is the truck traveling? 2. A 0.40 kg object is moving on a frictionless surface with a speed of 30 m/s. A force of 2.0 N is applied continually until the velocity of the object has been reversed. How long was the force applied? 3. A 0.058–kg golf ...
