A. 20 Joules
Explanation:
I'm taking the K12 Unit Test: Energy - Part 1 right now
Answer
given,
mass of glider = 0.23 Kg
spring constant = k = 4.50 N/m
spring stretched to 0.130 m
The springs potential energy =


U = 0.038 J
at x = 0,the only energy will be kinetic .


v² = 0.3304
v = 0.575 m/s
displacement of the glider
using conservation of energy



x = 0.678 m
The object will not be able to accelerate perpendicular to direction of motion
Answer:
18kg dog walking
Explanation:
the dog walking has more inertia than the boy and girl because its gravity is pulling it down to the earth
