a) What is the impulse the molecule delivers to the wall? b) If there are 1.5 × 1023 collisions each second, what is the average force on 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?
This document is a physics worksheet involving problems calculating momentum, impulse, force, time and velocity using momentum and impulse equations. The problems involve objects like trucks, golf balls, bowling balls, satellites and molecules colliding with surfaces.
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.
(Q. 51 Page 1 Impulse and Momentum Change Insert these words into the four blanks of the sentence: mass, momentum, acceleration, time, impact, weight, impulse, and force. (Not every word will be used.)
FACT: The product of the force and the time during which it acts is known as impulse. This is a vector quantity denoted with a (J). Therefore, Impulse = J = FΔt and the units are still kg· 𝑚 , which can also be written as a newton-second (N·s). FACT: Impulse is equal to change in linear momentum.
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.
