Calculate the kinetic energy of a 2.2 kg brick when it has a speed of 4.9 m/s.
A. 1.2 J
B. 17 J
C. 26 J
D. 220 J

State one advantage and one disadvantage of using a plane mirrior as a driving mirrior

Aweight lifter raises a 1600 n barbell to a height of 2.0 meters. how much work was done? w = fd a) 30 joules b) 3000 joules c) 320 joules d) 3200 joules

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
