The equations needed to solve this problem are outlined below. E = mc(T2 - T1) d = m/v P = E/tYou first need to work out the mass of the water. m = 1000 x 4.5 = 4500kg You then need ...
As the ball falls from a height to the floor, the gravitational potential energy stored in the ball will be converted to kinetic energy.The gravitational potential energy of the ball can be calculated usi...
Using the equation V2 = U2 + 2as, where V = final velocity, U = initial velocity, a = acceleration, s = displacement, we can substitute in the values given in the question t...
v2/r, towards the center of the circle.Remember that acceleration is the rate of change of velocity, not merely of speed. This means that the change in direction is im...
