Conservation of Momentum A collision when two objects end up sticking together can be modelled with the
following equation, if momentum is conserved in the accident then.
a) Momentum of two objects before collision = Momentum of two objects after collision
b) OR
M, V, + MY2 = (M, + M2) V3
So, if a truck with a mass of 3000kg is travelling at +35 m/s to the right, and a car
with a mass of 1000kg is travelling to the left at - 35 m/s.
1) What is the velocity (speed and direction) of the vehicles after the collision if they
are stuck together?
2) Based on your answer, explain which vehicle is safer to be in and why?

Which of the choices below is one of the primary gases found in the atmosphere? a. helium b. carbon dioxide c. nitrogen d. argon

The dot diagram represents the motion of the motorcycle as it moves from left to right

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
