A440 g model rocket is on a cart that is rolling to the right at a speed of 3.5 m/s. the rocket engine when it is fired, exerts a 8.0 n vertical thrust on the rocket. your goal is to have the rocket pass through a small horizontal hoop that is 20 m above the launch point part a at what horizontal distance left of the loop should you launch?

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

prolly a beacuse the momentuem the car has increases while going down hill

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
