Answer:
PE = M g H gravitational potential energy
KE - 1/2 M V^2 kinetic energy
PE = KE kinetic energy equal to initial gravitational energy
Answer:
The total distance at 7 s is:
Explanation:
<u>Distance due to the force</u>
We can use second Newton's law to find the acceleration.
Now, using the kinematic equation we will find the distance during this interval of time. Let's recall that the initial velocity is zero.
In the second part of the motion, the object moves at a constant velocity, as long as there is no friction between the object and the floor.
First, we need to find the final velocity of the first interval
So the second distance will be:
Therefore, the total distance is:
I hope it helps you!
Answer:
yes its okay i think so it is the correct answer
Answer:
Fr = 26.83 [N]
Explanation:
To solve this problem we must use the Pythagorean theorem, since the forces are vector quantities, that is, they have magnitude and density. Therefore the Pythagorean theorem is suitable for the solution of this problem.
