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?
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.
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.
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.
3 sty 2016 · Example: A 0.144 kg baseball approaches a batter with a speed of 30 m/s. The batter lines the ball directly back to the pitcher with a speed of 40 m/s. Find the impulse exerted on the ball. If the bat and ball were in contact for 0.012 sec, find the average force exerted on the ball by the bat.
Impulse Example (Impulse) The impulse of a force F, acting for a short time, A goalkeeper kicks a stationary football, of mass t, on a body is the quantity Ft, 0.6 kg, which then moves with a velocity of 35 ms−1. What impulse does the goalkeeper impart on the football? i.e. Impulse = Ft Using the formulae:
