How fast (to within 20%) would an object have to be traveling for its kinetic energy per gram to be
the same as the chemical energy density of gasoline (10 Cal/g) ?
(a) 1 m s-1 (b) 100 km s-1 (c) 10 km s-1 (d) 1000 m s-1
Please explain why. Thank you!
The correct answer is coming to be 10 m/s. I think there is
something wrong in the question

what is the kinetic energy in joules of a 46 gram object traveling at 4.7 m/s?
Kinetic Energy- KE-1 a) A 1,500kg car is traveling at 30.0m/s. How many joules of kinetic enorekye energy as the KE-2 a) Two objects with masses m -20.0 have? does the car b) Find the speed in km/hr for a 7.00kg bowling ball to have the same etic energy Find the ratio E/Ex g and my-60.0kg are both traveling with the same speed V. b) Two objects with identical masses m are traveling with speeds V1 20.0m's c) In part...
1. How much kinetic energy does an object of mass m traveling with a velocity vx in the x-direction have? 2. How much kinetic energy does an object of mass m traveling with a velocity ~v = vx ˆi + vy ˆj have? 3. Since the pythagorean theorem states that v ^2 = v ^2 x + v ^2 y , we can write the kinetic energy as K = 1/2mv^2 x + 1/2mv^2 y . Does this mean that...

How fast would a 89 person have to run to have a kinetic energy equal to the amount of energy used by a 40 Watt light bulb in 16 ? 2.6 m/sm/s 14 m/sm/s 3.7 m/sm/s 0.95 m/sm/s
How fast must an object move in order to have a kinetic energy that is 3.19 times its rest energy? Express your answer as a fraction of the speed of light to three decimal places.
Kinetic energy is the energy of motion. How much kinetic energy does a spherical asteroid with a 1 km diameter have if it is made out of iron (has a density of about 8 kg m-3) and hits Earth at a relative velocity of 10 km s-1?
A car is traveling at 12 m/s A. How fast would the car need to go to double its kinetic energy? B. By what factor does the car's kinetic energy increase if its speed is doubled to 24 m/s?
4. Kinetic energy is the energy of motion. How much kinetic energy does a spherical asteroid with a 1 km diameter have if it is made out of iron (has density of about 8 kg m-3) and hits Earth at a relative velocity of 10 km s-1? Convert your answer to megatons of TNT (1 megaton of TNT = 4.18 x 1015 joules).
