I can't answer this question without a figure. I've found a similar problem as shown in the first picture attached. When adding vectors, you don't have to add the magnitudes only, because vectors also have to factor in the directions. To find the resultant vector C, connect the end tails of the individual vectors.
<em>The red line (second picture) represents the vector C.</em>
B the waves transfer energy from its source
When force is applied on an object the object will not slide
So here object will remain in equilibrium after applying the force
So in this case the condition of equilibrium is maintained due to friction force that is applied on the object.
So here for equilibrium be can say

also we know that

we are given that
( applied force on the box)


So here this friction force on the cart is known as static friction

Answer:
KE = 9.6MeV
Explanation:
Given the relationships we understand that,

The Potential at point p, is given by the following formula

According to the graphic designed, you have,



The kinetic energy of the particle would be given by


A surf forms when waves get too high and "break"
