60/15 = 4
The KE of an object is proportional to the square of its speed.
Multiplying the speed by 4 increases the KE by (4)2 = 16 .

What has greater kinetic energy a car traveling at 35 miles per hour or a car traveling at 50 miles per hour?
Kinetic Energy is defined as the energy associated with motion. This is in contrast to potential energy which is associated with an entity's energy at rest, and it's potential for motion. Kinetic Energy can be calculated using this formula: KE = 0.5*Mass*Velocity^2, where KE = Kinetic Energy It is apparent by the formula that the same car traveling at a higher speed will have a greater kinetic energy than it does when traveling at a lower speed. Therefore, when the car travels at 50 mi/hr it has a higher kinetic energy than when it travels at 35 mi/hr. Let me just note that if we were talking about two different cars then we'd have to consider the weights of the cars.
Which has a greater kinetic energy a car traveling at 30 km h or a car half that mass traveling at 60 km h?
60. K= 1/2mv^2 therefore when v is larger, there is more kinetic energy
Why does an ocean liner traveling at 100km per hour would have more kinetic energy than a yacht traveling at the same velocity.?
The difference is the mass of the moving object: ocean liner some 10.000 to: yacht some 10 to Theory: W kin = kinetic energy m = mass v = velocity W kin = 1/2 * m * v² So the yacht would have to travel approx. 316 times faster than the ocean liner (when at 10 knots per hour) to have the same kinetic energy.
How much work has to be done on a 5 kg sled to increase its speed from 10 m s to 15 m s?
Work is simply a transfer of energy. Calculate the kinetic energy for both speeds, then calculate the difference. The formula for kinetic energy is KE = (1/2)mv2. If the mass is in kilograms, and the velocity (or speed) is in meter/second, the energy is in Joule.
What is the conserved sum of the potential and kinetic energy?
Total energy.
How many times does the kinetic energy of a car increase when traveling 60 mph as opposed to traveling 30 mph?
4 times (from v squared)
What energy is in a traveling bullet?
kinetic energy
What is the relationship between speed and kinetic energy?
The kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four. If there is a threefold increase in speed, the kinetic energy will increase by a factor of nine.
How do you increase the kinetic energy of a skateboard?
Since kinetic energy depends on mass and speed, you can increase either of these.
What is the result of increasing the temp of a gas?
The kinetic energy will increase
How do molecules gain kinetic energy?
Heating increase the kinetic energy.
What type of energy a car is traveling 45 mph have?
Kinetic Energy
Why drift velocity increases on increasing temperature?
because the kinetic energy of electron increase with increase in temperature. this increase in kinetic energy increase drift velocity
What is the kinetic energy of a 22500 lb truck traveling 55 mph?
The kinetic energy of a 22500 lb truck traveling 55 mph is 1/2mv2 is 3084.808kJ.
What variable can increase an objects kinetic energy?
the varible b can objects kinetic energy
What are the changes in the kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.
Does kinetic energy increase or decrease when a liquid changes to a gas?
the kinetic energy increases
