Kinematics

A projectile is considered to be in free fall when the only force acting on it is gravity. This means that the object is not being propelled or pushed by any external forces, and it is only subject to the force of gravity causing it to accelerate downward.

1mi = 1.6km

35km/h x 1mi/1.6km = 22mi/h (rounded)

301 kilometers per hour is 187.03 miles per hour.

To convert 750 feet per second to miles per minute, first convert feet to miles by dividing by 5,280 (since 1 mile = 5,280 feet). Then convert seconds to minutes by dividing by 60 (since 1 minute = 60 seconds). So, 750 feet per second is equal to 0.142 miles per minute.

The friction of running car tires on a road primarily causes kinetic energy to be converted into heat energy. This heat energy is a result of the resistance that occurs between the tires and the road surface, ultimately leading to a loss of energy in the form of heat.

8 miles per hour is approximately equal to 12.87 kilometers per hour.

Sound is the movement of a medium at frequencies we can hear. As it always involves movement of a medium, either a solid, liquid or gas to be transmitted it will involve kinetic energy at times.

Note that kinetic energy is the energy stored in a moving mass. Sound waves carry energy with a combination of both kinetic and potential energy. There are two moments in every cycle where there is no movement and therefore no kinetic energy. These two points are at the upper and lower peaks of the wave.

a seadoo can go 69 mph on flat water but with the water choopy it can go 65 mph

ATP, of course.

When the myosin head extends towards the actin thin filament it has in it's active site ADP and P +. So, when the stroke is over the ADP and P+ fall out and are replaced by ATP, which immediately metabolizes to ADP and P +.

The force of gravity is positive; there is no negative gravity.

If potential energy is not completely converted to kinetic energy, some of the potential energy may be transformed into other forms of energy such as heat, sound, or light. This can occur due to factors like friction or inefficiencies in the system. As a result, the total mechanical energy of the system may not remain constant, and some energy may be lost to other forms.

For the purposes of this explanation, velocity will be given in m/s. If it's starting position is the same as its stopping position, the radio controlled car will have an average velocity of zero meters per second. This is because average velocity is displacement/time interval. Displacement is change in position and is a vector quantity, which has magnitude and direction. Average velocity is the displacement/time interval, and is also a vector quantity, including the magnitude of the speed and its direction. If you start and stop walking at the same position, your displacement is 0m, even if you walked a distance of 100 miles, and your average velocity would be 0m/s.

There are 5280 feet in a mile, and 3600 seconds in an hour. Thus:

22 ft/s = (22/5280)(3600) = 15 mph.

The escape velocity of planet Jupiter is: ~133,097.71 miles per hour.

In a 15 mph crash without a seatbelt, the crash test dummy would experience the full force of the impact which could result in injuries such as head trauma, whiplash, or broken bones. Without the seatbelt to restrain the dummy's movement, it may also be thrown forward or out of the vehicle, increasing the risk of serious harm or death.

Mach 1.4 is approximately 1,062.72 miles per hour.

At 0 Kelvin, all molecular motion stops, so the kinetic energy of the vapor molecules would be zero. Therefore, the kinetic energy of the vapor would be reduced to zero.

For a top athlete it should take about an hour. A beginner prob an hour and a half

vf2 = vi2 +ad, where vf is the final velocity, vi is the initial velocity, a is acceleration, and d is displacement. In physics, velocity is the change in position of an object over a given time interval, and change in position is displacement, rather than distance.

To find displacement, manipulate the equation in the following manner. Assume vi is zero.

vf2 = 0 + 2ad

vf2 = 2ad

vf2/2a = 2ad/2a

vf2/2a = d

To convert miles per hour to kilometers per hour, you can multiply by 1.60934. Therefore, at 150,000 mph, you would be traveling at approximately 241,402 kilometers per hour.

No, the kinetic energy of a photoelectron is primarily determined by the frequency of the incident light (photon energy), not the intensity of the light. Increasing the intensity of light will increase the number of photoelectrons emitted but will not change their individual kinetic energies.

The fastest woman in recorded history is Florence Griffith-Joyner, who reached a top speed of 10.49 meters per second during her 100m world record run in 1988. This equates to approximately 37.6 km/h or 23.4 mph.

An object which is not moving is not experiencing any acceleration, other than the acceleration due to gravity, which, along with mass gives it its weight. The upward force (normal force) acting on the object is equal to but opposite to its weight, and all of the forces acting on the objects are in equilibrium so the net force is zero Newtons.

31 km = 19.26 miles (rounded)

77 km/h is approximately 47.85 mph.
