Answer:
Initial speed of stone = 12.25 m/s
Explanation:
Given:
Change in distance = 0.15 m
Force applied = 28 N
Find:
Initial speed of stone
Computation:
Using conservation of energy
(1/2)fs² = (1/2)(mv²)
fs² = (mv²)
(28)(0.15)² = (0.028)(v²)
v² = (28)(0.15)²/(0.028)
v = 12.25
Initial speed of stone = 12.25 m/s
