E) the sum of all the forces acting on the body is constant and nonzero. Answer: B . 13.Hence, kinetic energy is quadrupled. The mass of a body is halved and its speed is doubled. What happens to the kinetic energy of the body? and has rotational kinetic energy k1. If the radius of the sphere is halved and angular speed is doubled, then its rotational kinetic energy becomes k2. Which of the following options is correct ?How does the kinetic energy of a moving body depend on its speed? (i) Kinetic energy of a moving body is directly proportional to the square of the speed of the moving body. (ii) Kinetic energy of a moving body is directly proportional to the mass of the moving body. What happens to the kinetic energy when the velocity of a moving body is doubled?from rest, mass m 1 will rise and start gaining speed and higher gravitational potential energy. A maximum speed is reached when it is on a vertical posi-tion. Both masses will rotate with same angular speed !Energy conservation re-quires: 0 = m 1gr 1 m 2gr 2 + 1 2 I!2 = m 1gr 1 m 2 gr 2 + 1 2 (m 1r2 1 + mr 2)(v max r 1)2 Rearranging should ...Assuming we are talking about the mass of the satellite (and not the mass of the body being orbited), mass does not affect the orbital speed. How does the mass of a planet and its star affect the planet's orbit? The more massive a planet or star is, the stronger the gravitational force it exerts. It is this force that allows a planet or star ...The car, however, very rapidly increases Sam's speed from zero to the impact speed of the vehicle. The time taken for this is about the time it takes for the car to travel a distance equal to Sam's thickness—about 20 centimetres. The impact speed of Car 1 in our example is about 8.2 metres per second, so the impact lasts only about 0.024 seconds.By writing the formula for kinetic energy and using it to find a relation for the relative percentage errors of mass, speed and the kinetic energy, we can arrive at the required answer. Formula used:burning through the thread, the 5 kilogram body has a speed of 0.2 m/s. The speed of the 7 kilogram body is (in m/s) (A) 12 1 (B) 7 1 (C) 5 1 (D) 35 1 18. Multiple Correct: A satellite of mass M moves in a circular orbit of radius R at a constant speed v around the Earth which has mass ME. Which of the following statements must be true?
