Answer:
553.8 Watts
0.74 Hp
Explanation:
Power is work done per unit time, expressed as
P=W/t
Where P is power, t is time taken and W is work done.
Work is the product of force and perpendicular distance moved hence W=Fd where F is force and d is perpendicular distance.
Substituting W with Fd into the first formula then power is expressed as
P=Fd/t
Substituting F with 600 N, d with 6 m and t with 6.5 seconds then
P=600*6/6.5=553.84615384615 Watts
Rounded off as 553.8W
1 W=0.00134 british horsepower
553.8 W=0.00134*553.8=0.742719926544903597 Hp
Alternatively, we divide the watts by 746 hence 553.8/746=0.7424211177562
Rounding off, power is equal to 0.74 Hp
I think that your answer would be A. because matter never just goes away in any situation, even if it gets away from you.
Answer:
Honestly for me it's a bit too blurry. Sorry luv.:(
Explanation:
Answer:
U(0.0m) = 0J
U(5.5m) = 40.42 J
Explanation:
The gravitational potential energy is given by the following formula:

h: height
m: mass of the apple = 0.75kg
g: gravitational acceleration = 9.8m/s^2
When the apple is at 5.5m from the ground the gravitational potential energy is:

when the apple is on the ground you have:
