* Choose the correct
A force of kinetic friction fx = 5 N acts on a block for a distance d = 0A = 7 m. If
at point o, the block has a mechanical energy E. = 50 J, then the mechanical energy
at point A will be equal to:
E = 50)
E,=?

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

What explosion in the upper solar atmosphere releases about as much energy as millions of 100-megaton hydrogen bombs exploding simultaneously?
