Explanation:
A) we know that the magnitude of force
= 4.761×10^{-4} N
Also, net force = gravitational force - electrostatic force
B) F_net = F_g - F_e
m×a = m×g - 4.761×10^-4
a = g - 4.761×10^{-4}÷m
a= 9.8 - (4.761×10^{-4} /0.16×10^{-3})
a= 9.8 -2.975625
a= 6.82 m/s
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
