Answer:
(-3,2)
Step-by-step explanation:
when reflecting over the y axis all you have to do is flip the signs on the x values so it would be (-3,2)
Answer:
8 Joule
Step-by-step explanation:
Mass of block = 2 kg
Displacement = x = 800 mm = 0.8 m
Spring constant = k = 25 N/m
Potential Energy of a spring
Work done = Difference in Potential Energy
Work Done = Δ P.E.

⇒P.E. = 0.5×25×0.8²
⇒P.E. = 8 Nm = 8 Joule
Here already the spring constant and displacement is given so the mass will not be used while calculating the potential energy.
The area is 40 because you do 12 times two then eight times two then add the awnsers
