Answer:
25.2 cm
Explanation:
K = 1050 N/m
m = 1.95 kg
h = 1.75 m
By the conservation of energy, the potential energy of the block is converted into the potential energy stored in the spring
m g h = 1/2 x k x y^2
Where, y be the distance by which the spring is compressed.
1.95 x 9.8 x 1.75 = 1/2 x 1050 x y^2
33.44 = 525 x y^2
y = 0.252 m
y = 25.2 cm
Answer:
hich graph represents this system?
y = 2 x + 1. y = negative 4 x + 7.
On a coordinate plane, a line goes through (0, 7) and (1, 3) and another goes through (1, 3) and (2, 5).
On a coordinate plane, a line goes through (negative 4, 0) and (0, 7) and another line goes through (negative 4, 3) and (0, 1).
On a coordinate plane, a line goes through (0, negative 4) and (1, 3) and another goes through (0, 2) and (1, 3).
On a coordinate plane, a line goes through (0, 7) and (8, 5) and another line goes through (0, 1) and (8, 5).
