A 15kg box is pushed on a table with 20 Newtons of force. A frictional force of 5N opposes the motion of the box.
15kg
a) What is the net force acting on the box?
b) What is the acceleration of the box across the table?
c) What is the velocity of the box after 4 seconds if it started at rest at time Os?
d) How far did the box travel during those 4 seconds?
e) Sketch the graphs for velocity vs time, and position vs time for the first 5 seconds the
box is moving.

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
