A0.700-kg particle has a speed of 1.90 m/s at point circled a and kinetic energy of 7.20 j at point circled b. (a) what is its kinetic energy at circled a? 1.2635 correct: your answer is correct. j (b) what is its speed at circled b? 4.54 correct: your answer is correct. m/s (c) what is the net work done on the particle by external forces as it moves from circled a to circled b?

Arock is dropped from a cliff and reaches the ground in 2.70s. at the same time another rock is thrown horizontally from the same height with initial x velocity of 0.95 m/s. what distance will in x will the second rock cover?

How will the system respond to a temperature increase?
