Worksheet 9.1 Momentum and Impulse 1. The momentum of a 3000 kg truck is 6.36 × 104kg·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.
F net = Δ p Δ t , where Fnet is the net external force, Δ p is the change in momentum, and Δ t is the change in time. We can solve for Δ p by rearranging the equation. F net = Δ p Δ t. to be. Δ p = F net Δ t . F net Δ t is known as impulse and this equation is known as the impulse-momentum theorem.
Given that a force is being applied to an object during a time interval, then find the impulse (𝑱 𝒙). 𝐽 =∫ 〖 𝑑 =500∫ 𝑑 8 0 =500[ 𝑓 −〗 𝑖] 𝑓 𝑖 =500 [0.008𝑚 −0 ]=4𝑁∙ Now, use the impulse-momentum theorem (∆𝑃 =𝐽 ) to solve for the final velocity. ∆𝑃 =𝐽 𝑃 𝑓 −𝑃

Determine the impulse (I), momentum change (AP), momentum (p) and other values, A 7-ball collides with the 8-ball. m = kg A moving medicine ball is caught by a girl on ice skates. m = 10 kg A car is at rest when it experiences a forward propulsion force to set it in motion. It then experiences a second forward propulsion .orce to speed it up ...
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.
To calculate the impulse using Equation 9.3, we need to know the force function F (t), which we often don’t. However, a result from calculus is useful here: Recall that the average value of a function over some interval is calculated by. f (x) ave = 1 Δ x ∫ x i x f f (x) d x. where Δ x = x f − x i.
