Answer:
0.0316 m
Explanation:
Wok done = Energy change
Work done on the spring = Energy change of the block
Elastic Potential stored = Kinetic energy of the block
x =
x =
x = 0.0316 m
k = spring constant
m = mass of block
v = velocity of the block
x = compression of spring
The correct answer is A: H3PO4
ANSWER: 1.6N (forth option)
EXPLANATION:
E= Force x displacement
