it’s for an rc nitro car
I want to know if it would be possible to launch a meduim sized model rocket from a large R/C helicopter. i am talking about a vertical launch not shooting it horizontally like a gun. i was thinking that i would have to build some sort of launch platform but then i realized that the force of the rocket would throw the heli off balance. could i cut power to the heli and let it drop for a few seconds while the rocket launches? i really want to know if this will work for sure before i go out and trash the helicopter.
what is AMA? and why would it make this illegal?

1. A worker pulls a sled with a force of 80 N directed at an angle of 60 degrees above the horizontal over a level distance of 6 m. If a frictional force of 24 N acts on the sled in a direction opposite to that of the worker, what net work is done on the sled?
a. 240 J, b. 216 J, c. 144 J, d. 96 J
2. A model rocket sits on the launch pad until its fuel is ignited, blasting the rocket upward. During the short time of blast-off, as the ignited fuel goes down, the rocket goes up because:
a. momentum is conserved in this process
b. the fuel pushes on the ground
c. air friction pushes on the escaping fuel
d. the downward force of gravity is less than the downward momentum of the fuel
please explain why you believe the answers are what they are just in case yours are different than mine. thanks a lot guys!
3. A 10 g bullet with an initial speed of 100 m/s is fired horizontally into a 90 g wodden block initially at rest on a frictionless horizontal surface. The bullet passes completely through the block and emerges with a final speed of 20 m/s in the horizontal direction. How much mechanical energy is lost in this process?
a. 44.4 J
b. 50 J
c. 26.4 J
d. 20 J

Our neighbors were back out again tonight, only this time they brought out both the Navy and Air Force planes. During an earlier fly-by, the Navy plane actually got a damaged propeller. After a quick repair job back on the ground, the planes got ready to head back out once again. However, one of them wasn’t going to land…at least, not the traditional way…
this is my Align T-Rex 450 pro retrofitted with a GO PRO HD camera to the front in an attempt to follow and film my friends r/c air plane. also just for the hell of it

To model a spacecraft, a toy engine is securely fastened to a large puck, which can glide with negligible friction over a horizontal furface, taken as teh xy plane. The 7.0kg puck has a velocity of 2.00i m/s at one instant. Eight seconds later, its velocity is to be (5.00i + 7.00j)m/s. Assuming the rocket engine exerts a constant total horizontal force, find the components of the force. Find its magniutde.
