Resistance = (voltage) / (current)
Resistance = (52 V) / (2 A)
<em>Resistance = 26 ohms</em>
Answer:
<em>a. The cart's acceleration is 2 m/s^2</em>
<em>b. The cart will travel 100 m</em>
<em>c. The speed is 20 m/s</em>
Explanation:
a. The acceleration of the cart can be calculated using Newton's second law:
F = m.a
Solving for a:

The cart has a mass of m=15 Kg and is applied a net force of F=30 N, thus:


b.
Now we use kinematics to find the distance and speed:

The cart starts from rest (vo=0). The distance traveled in t=10 seconds is:


The cart will travel 100 m
c.
The final speed is calculated by:

The speed is 20 m/s
Just to give you a sense of scale, Jupiter is 2.5 times more massive than all the rest of the planets in the Solar System combined. Jupiter's diameter is 11.2 times larger than Earth. Jupiter is a very gaseous planet. The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. As the gases coalesced to form a protosun, the temperature in the solar system rose.
9.8 ms^-2 is acceleration
