The horizontal surface on which the block slides is frictionless.The speed of the block before it touches the spring is 6.0 m/s.
Aloiza [94]

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.

\dfrac{1}{2}m^2=\dfrac{1}{2}kx^2+\dfrac{1}{2}mV^2

mv^2=kx^2+mV^2

V^2=\dfrac{mv^2-kx^2}{m}

V^2=\dfrac{10\times 6^2-2000\times (0.15)^2}{10}

V = 5.61 m/s

From the given options,

V = 5.4 m/s

Hence, this is the required solution.

Strzała o masie 20g tuz po wystrzale ma prędkość 50m/s. Oblicz pracę wykonana przez zawodniczkę. Ile wynosi energia potencjalna
garri49 [273]

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
