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?
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.
Find the impulse. Solution: Impulse = FΔt = 5 × 1 = 5 N·s. What is impulse? Answer: Impulse is the product of a force and the time interval over which it acts on an object. It represents the change in momentum of the object and is given by the formula Impulse = F × Δ t. How does impulse relate to momentum? Answer: Impulse is equal to the ...

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.
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.
