Agrasshopper hops along a level road. on each hop, the grasshopper launches itself itself at an angle of 45 degrees. and achieves a range of 0.77 m. what is the average horizontal speed of the grasshopper as it hops along the road? assume that the time spent on the ground between hops is negligible.

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!
