Respuesta:

Explicación:

Dada

masa del bloque m=4\ kg

velocidad del bloque v=2.5\ m/s

constante del resorte k=30\ N-m

Cuando la masa impacta con el resorte, su energía cinética se transforma en energía potencial elástica del resorte

\frac{1}{2}mv^2=\frac{1}{2}kx^2

x=v\sqrt{\frac{m}{k}}

x=2.5\times \sqrt{\frac{4}{30}}

x=0.912\ m

Respuesta:

91 cm

Explicación:

masa, m = 4 kg

velocidad, v = 2.5 m/s

constante del resorte, K = 30 N/m

Supongamos que la compresión en el resorte es y.

La energía cinética del bloque se convierte en energía potencial elástica del resorte.

1/2 mv² = 1/2 Ky²

4 x 2.5 x 2.5 = 30 x y²

y = 0.91 m = 91 cm

Así, la máxima compresión en el resorte es 91 cm.

An aluminum rod is 10.0 cm long and a steel rod is 80.0 cm long when both rods are at a temperature of 15°C. Both rods have the
serg [3582]

Response:

0.9 cm

Clarification:

The following illustrates the calculation of the combined rod's length increase:

As established

Length increase = expansion of aluminum rod + expansion of steel rod

= 10cm \times 2.4e - 5\times (90-15) + 80cm\times 1.2e - 5\times (90-15)

= 0.9 cm

We simply summed the expansions of both the aluminum and steel rods to determine the overall increase in the joined rod's length, which must be factored in

A moving sidewalk 95 m in length carries passengers at a speed of 0.53 m/s. One passenger has a normal walking speed of 1.24 m/s
Maru [3345]
Answer: a) t = 1.8 x 10^2 seconds; b) t = 54 seconds; c) t = 49 seconds. Explanation: a) To determine the time of a stationary passenger on the sidewalk, we use the position formula. Given the constant speed of the walkway, we can calculate the time taken for set distances accordingly. This calculation extends into cases where combined velocities for walking are involved in subsequent queries.
