A spring is placed horizontally on a frictionless table. The spring constant of the spring is 50 N/m, and it is compressed 0.100 m by a 2.00 kg block. [a.] How much energy is stored in the spring?[b.] When the spring expands back to its resting position, it pushes the block away. What is the kinetic energy of the block as a result of this force?[c]. What is the velocity of the block as it is pushed away by the spring? *

where is the circuit diagram ?

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
