Answer:x=2 and x=3
Explanation:
Given
Potential Energy for a certain mass is

and we know force is given by


For Force to be zero F=0




Therefore at x=2 and x=3 Force on particle is zero.
Answer:
The force needed will be 5000[N]
Explanation:
Using the Newton's second law we have:
![F = m*a\\where\\F = force [N]\\m = mass [kg]\\a= acceleration [m/s^2]\\Replacing we have\\F = 0.025[kg]*200000[m/s^2]\\F = 5000 [N]](https://tex.z-dn.net/?f=F%20%3D%20m%2Aa%5C%5Cwhere%5C%5CF%20%3D%20force%20%5BN%5D%5C%5Cm%20%3D%20mass%20%5Bkg%5D%5C%5Ca%3D%20acceleration%20%5Bm%2Fs%5E2%5D%5C%5CReplacing%20we%20have%5C%5CF%20%3D%200.025%5Bkg%5D%2A200000%5Bm%2Fs%5E2%5D%5C%5CF%20%3D%205000%20%5BN%5D)
5 n to the right I think Hope this helps
Answer: 1960 N
Explanation:
The bear is sliding down at constant velocity: this means that its acceleration is zero, so the net force is also zero, according to Newton's second law:

There are two forces acting on the bear: its weight W, pulling downward, and the frictional force Ff, pulling upward. Therefore, the net force is given by the difference between the two forces:

From the previous equation, we find that the frictional force is equal to the weight of the bear:

Answer:
Q=1670J
Explanation:
Mass of ice: m=5g=0.005kg
Latent heat: lambda=3.34×10⁵J/kg
Heat received by ice: Q=m×lambda
Q=0.005×3.34×10⁵=5×334=1670J
