Answer:
B) Its horizontal velocity component is the same as it was just as it was launched
Explanation:
From dynamic we know that free falling objects had two components of velocity
The only acceleration that takes place in this case is gravity in the y-component of velocity
Since a=0 and that means that the velocity at the y-component changes with time but the horizontal component remain the same
This means that the horizontal velocity is not 0 but is <u><em>the same as it was just as it was launched</em></u>
Answer:
proton and neutrons
Explanation:
electron has negligible mass
Power is the amount of work done over a period of time. If you will put that into an equation, the formula of power will be:
P = W/t
Where:
P = power
W=work
t = time
Your problem already provides you with work and time so all you need to do is divide:
P = W/t
P = 50J/30s
P = 1.67 W
