Answer:
Answer is 183.6 J
Explanation:
Using the Physics reference sheet the formula for Potential energy is
(mass) x (gravity) x (height)
Mass= 1.2
Gravity I used is 9.81 (use 10 to get the answer most schools use)
Height= 15.6
Answer:
100years later
Explanation:
Because the lights will arrive at world after 100 years later.
Work = force x distance
F= 2.5
D= 3
Work = 2.5 x 3 =7.5
Work = 7.5 J
J=Jules (Jules is the unit uses to calculate work)
Yes. On a circular path, the direction of motion is constantly changing. Change of direction is acceleration, even at constant speed.
