Answer: 10 m/s
Given:
Force, F = 25 N
Initial velocity [tex]u=0 m/s^{2}[/tex]
Distance moved, s= 4 m
mass, m = 2 kg
Formula Used:
[tex] F = ma [/tex]
where a is the acceleration.
equation of motion:
[tex]2as=v^{2}-u^{2}[/tex]
First, we would calculate the acceleration from the formula for force.
[tex]a= \frac{F}{m}=\frac{25}{2}m/s^{2}[/tex]
Using the equation of motion, we can find the final velocity now:
[tex]2[/tex]×[tex]\frac{25}{2}[/tex]×[tex]4= v^{2}-0^{2}[/tex]
taking the square root on both sides and ignoring the negative sign:
v= 10 m/s
