A block slides down a 600m inclined plane as shown in the picture below starting from rest. What is the speed of the block when it reaches the bottom of the incline

Athin, square metal plate measures 14 cm on each side and has emissivity of 0.60. the plate is heated to a temperature of 745°c. what is the rate at which the plate radiates energy ? the stefan-boltzmann constant is 5.67 × 10-8 w/(m2 ? k4). remember that the plate will radiate energy from both its top and bottom surfaces.

If the speed of a particle triples ,by what factor does its kinetic energy increase?
