Net force help please.
nekit [7.7K]
The net force is the total force. Add 4 and 2 together and you get 6. Since 5 N are pushing against it, you subtract that from 6. The net force is 1 N.

If spring has a spring constant of 500 N/m and is stretched .50 meters,how much energy is stored in the spring ((show work for f
Free_Kalibri [48]

Answer:

The energy stored is: 62.5 Joules

Explanation:

Given

k = 500N/m --- spring constant

x = 0.5m --- stretch

Required

The amount of energy

This is calculated as:

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

U = \frac{1}{2} * 500N/m * (0.5m)^2

U = 250N/m * (0.5m)^2

U = 62.5\ J

A 61.5 KG student sits at a desk 1.2 5M away from a 70.0 KG student. What is the magnitude of the gravitational force between th
muminat

mass of two students are

m_1 = 61.5 kg

m_2 = 70 kg

distance between them is given as

r = 1.25 m

now gravitational force between them is given as

F = \frac{Gm_1m_2}{r^2}

now plug in all values

F = \frac{6.67\times 10^{-11} \times 61.5 \times 70}{1.25^2}

F = 1.84 \times 10^{-7} N

so above is the force of gravitation between them
