Answer:
the body has energy due to its constant motion. it means it moves in a uniform acceleration which has zero velocity
Explanation:
Uniform or constant acceleration is a type of motion in which the velocity of an object changes by an equal amount in every equal time period.
Answer:
Point a
Explanation:
The potential energy of an object is given by :
P = mgh
m is mass, g is acceleration due to gravity, h is height above ground level.
Potential energy is directly proportional to the position of an object.
In the attached figure, the maximum height is shown at point (a). It means it will have maximum potential energy at a as compared to b,c and d.
Answer:
78 percent
Explanation:
I guess that's the right answer
Neither of those questions makes sense, and I believe that you should not waste your time worrying about them.
#61 gives you a lot of information about a ball, and then asks a question about a glove.
#62 gives a mysterious equation, doesn't tell you what either of the variables represents, and then asks for a quantity without ever telling us how that quantity is related to the equation.
Personally, my response to both questions would be "Insufficient information given".
