Homework Help Overview

The discussion revolves around the effects of momentum when a brick is dropped onto a moving toy truck. The scenario involves a 1.5 kg brick and a 2.5 kg truck, with the truck initially moving at 0.80 m/s across a level surface.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the momentum conservation principle, questioning how the vertical drop of the brick affects the horizontal motion of the truck. There is also a humorous inquiry about the truck's stability under the brick's impact.

Discussion Status

Some participants have attempted to apply the conservation of momentum formula to find the new velocity of the truck and brick system after the brick lands. There is an indication that one participant believes they have arrived at the correct answer, while another expresses uncertainty about the concepts involved.

Contextual Notes

One participant notes a lack of prior exposure to this type of problem in class, indicating potential gaps in understanding the vertical and horizontal components of motion.

a 1.5 kg brick is dropped vertically onto a 2.5 kg toy truck, which is moving across a level floor at 0.80 m/s. With what velocity do the truck and brick continue to movie, after the brick has landed on the truck.

i've dealt with only horizontal movements andd i haven't covered this yet in class sooo ineeed helppp lol would the truck go through the floor if the brick hit it ? lol =S
 
Physics news on Phys.org
nevermind i got the answer now its 0.50 m/s lol
 
m1V1=m2V2
where m1=2.5Kg V1=0.8m/s m2=1.5+2.5=4Kg V2=?
i suppose this is the answer because there is no vertical component of the bricks force acting on the truck...
 
i got it right then...:)
