A3.0 kg puck slides due east on a horizontal frictionless sur-face at a constant speed of 4.5 m/s. then a force of magnitude 6.0 n, directed due north, is applied for 1.5 s. afterward, a. what is the northward component of the puck’s velocity? a. 0.50 m/s d. 4.0 m/s b. 2.0 m/s e. 4.5 m/s b. what is the speed of the puck? a. 4.9 m/s d. 7.5 m/s b. 5.4 m/s e. 11 m/s c. 3.0 m/s c. 6.2 m/s

We know that the formula to of acceleration is given by,

Re-arrange to the Velocity,

(1)

We know as well for second Newton's law is,

We can re-arrange for the acceleration, so

(2)

Replacing (2) to (1),

Our values are,

Substituting the values,

We have two components of a net velocity, so we can calculate the direct force through,

your answer would be fusion

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
