Answer:
200J
Explanation:
200J is 100%, 10% of 200J would be 20J
Answer:
60 m
Explanation:
Since it goes 6 m per second, and it goes for 10 seconds, then you'd just multiply 6 x 10, to get that the ball would roll 60 m in 10 seconds.
The acceleration a free falling body experiences due to gravity will always remain the same. It will always be -9.8 m/s^2.
Thus, the downward velocity of the body will always be increasing (or decreasing, however you want to think about it) because gravity is acting upon it.
The distance the body has fallen will increase faster and faster over time because its velocity is increasing.
PV/T =C
P.V1/T = 1/2P.V2/3/4T
V1= 4V2/6
V2/V1 = 6/4 =3/2
