The resultant force of both forces is 15.62 N.
<h3 /><h3>What is resultant?</h3>
The Resultant of forces is a single force obtained when two or more forces are combined.
To calculate the resultant of the force, we use the formula below.
Formula:
- R = √[a²+b²-2abcos∅]..................... Equation 1
Where:
- R = Resultant of the forces.
- ∅ = Angle between both forces
From the question,
Given:
Substitute these values into equation 1
- R = √[8²+10²-2×8×10cos120°]
- R = √[64+100-160cos120°]
- R =√ [164-160(-0.5)]
- R = √[164+80]
- R = √(244)
- R = 15.62 N
Hence, the resultant force of both forces is 15.62 N.

#SPJ1
Answer: 10 m/s
Given:
Force, F = 25 N
Initial velocity
Distance moved, s= 4 m
mass, m = 2 kg
Formula Used:
where a is the acceleration.
equation of motion:
First, we would calculate the acceleration from the formula for force.
Using the equation of motion, we can find the final velocity now:
××
taking the square root on both sides and ignoring the negative sign:
v= 10 m/s
is there more to this? if so i would love to help you!!
