A 50kg block is dropped from a point 10m above as shown in the fig above. if the force constant of the spring is 4.0 x 104Nm-1, find the maximum compression of the spring
[g = 10ms-2]
A.
1.25m
B.
0.50m
C.
0.25m
D.
0.05m
Correct answer is B
P.Emgh = 12 * k * x2
mgh = 12 * k * x2
50 * 10 * 10 = 12 * 4 * 104 * x2
→ x2 = 5000∗24∗104
→ x = √[0.25]
: x = 0.50m
