Find the impulse that acted on the object if, after the collision, it moved at the following velocities: a) +8 m/s b) –3 m/s 10. A nitrogen molecule with a mass of 4.7 × 10-26 kg, moving at 550 m/s, strikes the wall of a container and bounces back at the same speed. a) What is the impulse the molecule delivers to the wall?
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?
Physics 30 Worksheet # 1: Momentum 1. Calculate the momentum of a 1.60 x 103 kg car traveling at 20.0 m/s. 2. Calculate the momentum of a 2.50 x 103 kg truck traveling at 110 km/h. 3. How fast is a 1.50 kg ball moving if it has a momentum of 4.50 kg.m/s? 4. A 75.0 g ball is rolling at a speed of 57.0 cm/s. Calculate the ball’s momentum. 5.
Worksheet Phys 201: Chapter 9 Impulse and Momentum Before we begin the problems, it helps to list your known’s and unknowns/what we are solving for. This helps with organization by identifying the what the problem is asking for. Also, red represents the solution. Section 9.2: Solving Impulse and Momentum Problems 12)
The worksheet tests understanding of how to calculate these values for various scenarios using the fundamental equations for momentum and impulse. This document is a physics worksheet involving problems calculating momentum, impulse, force, time and velocity using momentum and impulse equations.
Momentum and Impulse 1. What is the momentum of a 1200 kg car travelling at 100 km/h down the freeway? 2. A 5.00 kg ball is thrown towards a wall with a speed of 6.00 m/s. The ball hits the wall and rebounds backwards with a speed of 2.00 m/s. Calculate the change in momentum of the ball. 3. What is the impulse of the collision in question 2? 4.
1. A force of 20.0 N is applied to a 3.00 kg object for 4.00 seconds. Calculate the impulse experienced by the object. 2. A 1200 kg car traveling at 20.0 m/s speeds up to 30.0 m/s. What is the impulse experienced by the car? 3. A 1500 kg car accelerates from 55.0 km/h to 90.0 km/h. Calculate the impulse experienced by the car. 4.
