Energy has many different forms: energy is the energy of motion, for every moving object and living thing; energy is a stored energy, ready to be used and converted into other types of energies.

Kinetic and potential energy are both proportional to the of the object under study. If you take a -kg ball and place at the top of an inclined plane, at 4 m from the ground, it will have a energy of 392 J. While it slips down the plane, its energy increases, its energy decreases, and its energy remains constant. If we neglect other factors such as friction, we can assume that the ball, once arrived at the bottom of the plane, it will have a velocity of m/s.

The choices for the blanks are: 0, 10, 86, 392, directly, height, inversely, kinetic, mass, potential, total and velocity.

Ababy stroller is a rest on top of a hill which is 10 m high. the stroller and baby have a mass of 20 kg. what is the potential energy of the baby and stroller?

The boy of mass 30 kg is at r1= 2 meters from the fulcrum. of the girl is 45 kg, at what r2 must she sit so that they are balanced ?

1. the materials manager for a billiard ball maker must periodically place orders for resin, one of the raw materials used in producing billiard balls. she knows that manufacturing uses resin at a rate of 50 kilograms each day, and that it costs $.04 per day to carry a kilogram of resin in inventory. she also knows that the order costs for resin are $100 per order, and that the lead time for delivery is four (4) days.2. at what point should resin be reordered? a. 0 kilograms remainingb. 50 kilograms remainingc. 200 kilograms remainingd. 400 kilograms remaininge. 500 kilograms remaining3. if order size was 1,000 kilograms of resin, what would be the length of an order cycle? a. 0.05 daysb. 4 daysc. 16 daysd. 20 dayse. 50 days4. if the order size was 1,000 kilograms of resin, what would be the average inventory level? a. 50 kilogramsb. 200 kilogramsc. 500 kilogramsd. 800 kilogramse. 1,000 kilograms5. if the order size was 1,000 kilograms of resin, what would be the daily total inventory costs, excluding the cost of the resin? a. $5b. $10c. $20d. $25e. $40
