When you click the tool menu , along with a stopwatch and rulers, you will see two tools you may not have used before. Clicking the dot tool will bring up a marker like this: . You can drag the marker to mark a position such as the starting point of the puck. The 2 on the tool means that you can place up to 2 markers. This can be useful for marking the starting and ending points for the puck.
Clicking line tool will bring up a horizontal line you can drag into place. This can be useful for measuring changes in height since the puck moves horizontally and vertically.

Without collecting any data, describe the motion of the puck while it is on the curved portion of the ramp. Assume we can ignore friction. Be sure to include words like "velocity" and "acceleration".

moving ball hits still ball. mover stops, hit ball moves. momentum transfer.

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.

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
