A 45.0 kg skater is skating at a speed of 12.0 ms The skater coasts to a speed of 6.00 ms How much kinetic energy has the skater lost
A jogger runs at an average speed of 5 ms for 3 minutes then finishes with an average speed of 4 ms for 2 minutes What is his average speed in ms for the run
A 14 kg cart is coasting down a street at a steady speed of 7 ms what is the kinetic energy of the cart
Kinetic energy = 1/2 M V2 = 0.5 x 14 x 49 = 343 joules
The tangent of an angle equals the ratio of the
Sine of the angle to its cosine.
A rock weighing 98 newtons is pushed off the edge of a bridge 50 meters above the ground What was the potential energy of the rock before it began to fall
How much heat energy would it take to melt a 20 kg block of lead that was at 24 degrees Celsius
A 50 kg cannon ball is shot horizontally from a cannon at a speed of 80 ms At this speed its kinetic energy will be joules
Kinetic Energy = 1/2 M V2 = (25) (80)2 = 160,000joules.
This term is the center of interest for an artwork
