Calculate the rock’s momentum as it strikes the ground. 1. A force of 20.0 N is applied to a 3.00 kg object for 4.00 seconds. Calculate the impulse experienced by the object. 2. A 1200 kg car traveling at 20.0 m/s speeds up to 30.0 m/s. What is the impulse experienced by the car? 3. A 1500 kg car accelerates from 55.0 km/h to 90.0 km/h.
Directions: Answer the following questions concerning the conservation of momentum using the equations below. Show all of you work to receive credit. 1. When these two freight cars of different mass collide and couple, what will be their resultant velocity? 2. A 2 kg blob of putty moving at 4 m/s slams into a 6 kg blob of putty at rest.
This document is a momentum worksheet that provides information about momentum through true/false questions, fill in the blank questions, and example problems calculating momentum given mass and velocity.
Mya and Kengo are both at rest and facing each other on roller skates. Mya has a mass of 65 kg and Kengo has a mass of 40 kg. When they push against each other Mya moves at a speed of 6 m/s. How fast does Kengo move? How much work did they do pushing against each other?
Suppose you are traveling in a bus at highway speed on a nice summer day and the momentum of an unlucky bug is suddenly changed as it splatters onto the front window. a) Compared to the force that acts on the bug, how much force acts on the bus.
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.
In order to apply the law of conservation of momentum, what should the system be? One ball or both billiard balls? A hockey puck of mass 0.17 kg and velocity 5 m/s is caught by a 0.5 kg mitten laying on the ice.
