U4 L11 Show What You Know: Factors That Affect Kineti Refer to the kinetic energy formula to answer the following question. KE=mv2 2 An object with a mass of 10 kg will have two times the amount of kinetic energy as a 5 kg object that is travelling at the same velocity. Desk 1 1 2 3 4 5 Sign

(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) 13. When you throw a ball, the work you do to accelerate it equals the kinetic energy the ball gains. If you do twice as much work when throwing the ball, does it go twice as fast? Explain.

How much work does the force do on a particle as it moves from to

A person drops a pebble of mass m1from a height h, and it hits the floor with kinetic energy K. The person drops another pebble of mass m2, from a height of 2h , and it hits the floor with the same kinetic energy K. How do the masses of the pebbles compare?

The goose has a mass of 24.1 lb (pounds) and is flying at 11.1 miles/h (miles per hour). What is the kinetic energy of the goose in joules? Enter your answer numerically in joules.

ACTIVITY 5 ODL STEM 12A The energy consumed by a o.8okW electric drill is 45 kJ in 1. _hour/s. What is the speed of a 3.okg object when its kinetic energy is 5.0J? Express your answer in ft/s (feet/second) 2. 3. What is the speed of the same object in #2 if the object has a weight of o.225|b? What is the ratio of energy consumption of a person who moves minimally when his/her requirement in moving is 8 MJ of energy per day. Express your answer in Watts. 4.

A 181-kilogram object was pushed from rest to a speed of v meters per second, doing 22836.5 joules of work in the process. Find its speed. The speed of the car is -- meters per second. Note: Use g=9.81 m/s². Round off your answer to the second decimal place. Do not include the unit. Do not put commas in between digits. For numbers that are less than one, put a zero before the decimal point. For example, 0.56 and 0.123. From the previous item, A 181-kilogram object was pushed from rest to a speed of v meters per second, doing 22836.5 joules of work in the process. The car moves 9.4 meters during this time. Find the horizontal force exerted on the car. The horizontal force exerted on the car is -- newtons. Note: Use g=9.81 m/s2. Round off your answer to the second decimal place. Do not include the unit. Do not put commas in between digits. For numbers that are less than one, put a zero before the decimal point. For example, 0.56 and 0.123.

A truck pulls a sled loaded with different kinds of vegetables at a certain distance. Suppose the sled with the load had an initial speed of v1 = 3.72 m/s and the total mass of the sled with the load is m = 1,619 kilograms. If the total work done on the sled with the load is Wtot = 18,488.6 joules, what is its final speed? %3D Hint: Use work-energy theorem.

A weight lifter lifts a 380-N set of weights from ground level to a position over his head, a vertical distance of 2.40 m. How much work does the weight lifter do, assuming he moves the weights at constant speed? My answer was 855 This was my feedback Please fix this Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. J

Compute the kinetic energy of an 1800 lb automobile traveling at 30 mi/hr, How many times as great is the kinetic energy if the velocity is doubled. Ans. Four times
