The time it takes you to slow to 5 m/s will be 5 seconds. Newton's first equation of motion is employed in a given problem.
The change of displacement with respect to time is defined as the velocity. Velocity is a vector quantity. it is a time-based component.
Given information;
Final velocity,v= 5 m\sec
Initial velociyt,u=20 m/sec
Acceleration,a=- 3m/s²
Time period,t=-?
From Newton's first equation of motion as;
[tex]\rm v = u+at \\\\ t= \frac{v-u}{a} \\\\ t= \frac{5 \ m/sec -20 m/sec }{-3 \ m/sec^2} \\\\\ t= 5 \ sec[/tex]
Hence, the time it takes you to slow to 5 m/s will be 5 seconds.
