Friction is a force that acts in a direction opposite to motion. If there were not force of friction, a baseball player would never stop and would be continuously moving in the direction of motion. Balanced forces do not cause a nonmoving object to start moving.
Answer:
3.53 second
Explanation:
The formula for the height is
When it hits the ground, the height is zero.
So, put h = 0 in the above equation
Take positive sign
t = 3.53 second.
Thus, the time taken to hit the ground is 3.53 second.
It decreased it because the velocity is sjsjdjdjdjdjdjdjdjdjdjfjfjfjfjdjrfkrorkd
True: a scientific fact is something that is absolute and unchanging.
Answer:
Explanation:
Given
Potential Energy of a particle is given by
For minimum or maximum Potential Energy differentiate U(x) w.r.t x
putting
To know minimum value check
at x=-2
so at x=-2 potential energy is minimum
