Homework Statement Homework Equations The Attempt at a Solution I do not understand what it means by maximum Homework Statement Homework Equations The Attempt at a Solution for label the force, should I show the arrow pointing downwards...

it changes as in, the pellet is going backwards = -velocity therefore even more velocity in the forward motion by the car to balance out the momentum total?

The momentum is conserved for both.

Oh so, with the metal plate, it appears the collision was elastic meaning, kinetic energy is conserved, therefore the car will travel further as no loss of energy, whereas the clay absorbed some of the energy before it reached the car, meaning not all of the total initial energy was transferred...

Homework Statement Homework Equations The Attempt at a Solution My guess is that, the with the modelling clay the pellet is absorbed initially by the clay, (it sicks in) some of the energy is lost through the clay but some is also transferred to the car giving it the means to...

but doesn't 180m/s seem to big of a value for the velocity.

Are you being serious or troll? I can't tell :cry: If you could outline what is actually good and makes sense in my answer would make me more confident.

anyone help?

Homework Statement Homework Equations Mg deltha H 1/2mv^2 p=mvThe Attempt at a Solution I believe statement to do with the Gravitational energy is correct, considering the equation I listed. I would have to agree with statement 2 since gpe=keHere is what I am thinking, I disagree with...

Lets say if there was an experiment in which: A toy car with modelling clay attached to it, and a pellet is fired at it, the pellet sticks into the clay and the toy car moves forward. Now if it is replaced with a metal plate attached to the toy car instead of the clay, the pellet rebounds...

Never mind, you are indeed correct and I apologise, I just realized I read the value for distance differently, the kinematic equations gave a value of 1.06m/s which is good enough for me. However now I have to state an assumption in order to apply the equation I used.

It cannot be, the value is way off.

Homework Statement A pellet is fired from a gun. the Pellet is fired horizontally into the a toy car, which has modelling clay attached to it. The pellet remains in the clay as the car moves. The car travels a distance of 0.069M before coming to a rest at 1.3s show that the speed of the...
