I didn’t quite understand your question, perhaps typos?
Answer:
V = 5.4 m/s
Explanation:
It is given that,
Let mass of the block, m = 10 kg
Spring constant of the spring, k = 2 kN/m = 2000 N/m
Speed of the block, v = 6 m/s
Compression in the spring, x = 15 cm = 0.15 m
Let V is the speed of the block moving at the instant the spring has been compressed 15 cm. It can be calculated using the conservation of energy of spring mass system.




V = 5.61 m/s
From the given options,
V = 5.4 m/s
Hence, this is the required solution.
Answer:
Explanation:
masie m = 20g = 20/1000 = 0.02kg
prędkość v = 50m/s
P.E = K.E = ½mv²
P.E = ½ × 0.02 × 50²
P.E = 25 J
pracę wykonana = P.E = 25J
