Explanation:
The given data is as follows.
Spring constant (k) = 78 N/m, 
Mass of block (m) = 0.50 kg
According to the formula of energy conservation,
mgh sin 
h = 
= 
= 0.64 m
Thus, we can conclude that the distance traveled by the block is 0.64 m.
Answer:
608kg
Explanation:
Formula : <u>Kinetic</u><u> </u><u>energy</u><u> </u>
½ ×mass x speed²
<u>47500</u>
½×12.5²
=608 Kg
Increase .... decrease .... presumably it's the "best shape" for a body which has been formed by the gravitational force
