Answer:
yeah righto the correct answer mate would be D) :)
Answer:
Explanation:
The stored elastic energy in the spring helps the box to rise to a height of .75 m
So stored elastic energy = potential energy attained
1/2 k d² = mgh , k is spring constant , d is compression in spring , m is mass of box , h is height attained .
Putting the values
.5 x 220 x d² = 4 x 9.8 x .75
d² = .2673
d = .517 m
51.7 cm .
10 is the number that is subtracted from it is the MINUEND
4 is the number being subtracted its then the SUBTRAHEND
6 is the result it is then the DIFFERENCE
so the correct term for 4 is SUBTRAHEND
