Momentum and Impulse. 1. The momentum of a 3000 kg truck is 6.36 × 104 kg·m/s. At what speed is the truck traveling? 2. A 0.40 kg object is moving on a frictionless surface with a speed of 30 m/s. A force of 2.0 N is applied continually until the velocity of the object has been reversed. How long was the force applied? 3.
Determine the impulse (I), momentum change (Δp), momentum (p) and other values. A 7-ball collides with the 8-ball. A moving medicine ball is caught by a girl on ice skates.
Calculate the following: (a) the velocity of the players just after the tackle, (b) the decrease in kinetic energy during the collision. 06-43) This is a collision & momentum is conserved during all collisions & explosions.
What impulse is and the two ways in which it can be calculated. What moments are and how to calculate them. Example (Momentum) A biker and their motorbike have a combined mass of 320 kg and are travelling along a straight horizontal road at 22 ms−1.
F net Δ t F net Δ t is known as impulse and this equation is known as the impulse-momentum theorem. From the equation, we see that the impulse equals the average net external force multiplied by the time this force acts. It is equal to the change in momentum.
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? b.
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.
