Answer:
Yes Newton's laws apply to small objects
EX: Newton s first law
when body at rest always want to be at rest
or body at motion always want to be at motion
unles an external force acts upon it
for example a eraser on the table will be at rest
if so e apply some force then it comes motion
so, Newton s law apply to small object s
Answer:
m = 20[kg]
Explanation:
This problem can be solved, using kinematic equations and then applying Newton's second law. First we must find the acceleration and then replace it in the equation of Newton's second law.
Initial data:
Vo = initial velocity = 0 [m/s]
t = 3[s]
T- F = -m*a
T - m*g = m*a
We can assume a value for tension T equal to 196 [N].
Note: For this problem it is important to assume a tension value, otherwise, it is impossible to determine the value of mass m, in Newton's second law equation.
Answer:
A d-t graph's slope is equivalent to the speed and direction while a v-t graph's slope is equal to its acceleration. A constant slope for a d-t graph means that the speed is constant. The area underneath a v-t graph would be its distance.
