A mass of $0.5 kg$ moving with a speed of $1.5 m /$ $s$ on a horizontal smooth surface, collides with a nearly weightless spring of force constant $k =$ $50 N / m$ . The maximum compression of the spring would be

Options:

Answer:

Solution:

Apply law of conservation of energy, $\frac{1}{2} mv^{2} = \frac{1}{2} kx^{2} \Rightarrow mv^{2} = kx^{2} or 0.5 \times (1.5)^{2} = 50 \times x^{2} ∴ x = 0.15 m$
