A 1250 kg race car accelerates uniformly from rest to 30.0m/s in 4.00s, on a horizontal track with a coefficient of friction of 0.60. what is the average power output caused by the applied force of the car engine?

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) sketch the trajectory using an appropriate coordination system. b) how long for the projectile to reach the ground. c) how far did projectile travel horizontally before striking the ground. d) determine the projectilex & y position at t-1.3s e) determine the magnitude and direction of projectile velocity at t= 1.3s f) determine the magnitude and direction of projectile acceleration at t-1.3s

Which of these describe conduction transfer of heat between two objects that are touching transfer of heat by the actual movement of war matter the process in which energy is imitated by one of the object transmitted through space and absorbed by another a process in which energy is released by the molecules breaking apart

Occurs when an energy source transfers heat directly to another subject space; an example would be an object becoming warm by sitting in the sunshine
