The diagram shows a ball of 0.4 kg mass being released from a height of 5 m above the ground. A is the initial position of the ball. B is the position of the ball at the moment before it hits the ground.
1)what is the gravitational potential energy of the ball at position A?
[gravitational field strength, g = 10 N m s-2]
2)the ball achieves a maximum speed of 10 m s-1 at position B. what is the kinetic energy of the ball at position B?
3)compare the amount of energy obtained in question 1&2. give an explanation for the result.

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
