What would be the skaters speed if all the potential energy could be converted into kinetic energy?
Clearly, that depends on the amount of potential energy. If given the height, calculate the potential energy with the formula for gravitational potential energy (PE = mgh). If mass is not given, you can assume any mass (it doesn't affect the result), or use a variable "m". Then, assuming it gets converted to kinetic energy, use the formula for kinetic energy (KE = (1/2)mv2), replace the KE with the energy you calculated before, and solve for v (the speed).
A skier who has more blank energy than a skier at the bottom?
A skier at the top has more potential energy
What is the fastest a human has kicked a football in mph?
Sporting Lisbon's Brazilian left-back Ronny "Homem-Bomba" (human bomb) Heberson holds the record, with a free kick against Naval that has been measured to be moving at close to 132 mph. Watch it at: http://youtube.com/watch?v=cSzwIBeihXA
How do you plot a distance time graph when you are given a velocity time graph?
The area under a v/t graph is how far you've gone. Choose a point on the time axis, read off the speed and find the area underneath. If its a straight line graph, all you have to do is find the area of the triangle. This area is the distance travelled in this particular time. Repeat for several more points on the time axis. Plot distance against time.
Because when it hits the ground its momentum makes it continue to fall for a fraction of a second causing the part touching the ground to collapse slightly (depending on how hard the ball is). The collapsed part then straightens itself out again rapidly, flicking the ball up as a bounce.
Why is the body moving with a uniform velocity is zero?
The body is not zero, but the sum of all forces on it is.
-- "Uniform velocity" means no acceleration.
-- Acceleration is force/mass .
-- If acceleration is zero, that's an indication that force must be zero.
In a closed system energy is equal to potential energy plus kinetic energy?
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
V2 X W divided by 2G or 64. Or, Velocity squared times Weight of the object (in motion) divided by 2 Gravity or 64 equals the force of impact of the object in motion.
How long will it take to travel 126.2 at 37.2 miles per hour?
It takes 3 hours 24 minutes to travel 126.2 miles at 37.2 miles per hours
What is the relationship between stream erosion and kinetic energy?
It is direct, and the amount of stream erosion increases, kinetic energy increases also.
What is the top speed of a Yamaha Grizzly 125 ATV?
Why is the term energy is closely linked with the idea of force and motion?
Mechanical energy is equal to force x distance. Actually, work is defined this way, but you can think of work as a transfer of mechanical energy.
