PLEASE HELP ASAP (TEST) NEED EXPLANATION TOO Volleyball: Court dimensions: 18m long - 9m wide.
Net height: 2.23m for women
-If a volleyball is served with a diagonal velocity of 10m/s at an angle of 42◦ from the horizontal.
a. Does it hit the net?
b. Find out if it lands in the court or not.
c. What is the final (diagonal) velocity of the ball?
d. What is the landing angle of the ball?

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.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
