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?
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?
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.
Some impulse and momentum practice problems in one dimension are presented and solved. All these problems are helpful for your homework and/or the AP Physics 1 test. For better practice, all subjects are broken down into sections.
1) A 2.5 kg ball strikes a wall with a velocity of 8.5 m/s to the left. The ball bounces off with a velocity of 7.5 m/s to the right. If the ball is in contact with the wall for 0.25 s, what is the force exerted on the ball by the wall? (assume the force is constant) v ! ∑ F = ?
5 dni temu · The cart experiences an impulse of 200 N·s. Problem 2: A tennis racket applies an impulse of 10 N·s to a tennis ball over 0.2 seconds. What is the average force exerted by the racket? Solution Rearrange the impulse formula to find force: F = Impulse / Δt. Substitute the values: F=10 N·s / 0.2 s = 50 N. The impulse delivered to the ball is ...
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.
