s=ut+$\frac{at^{2}}{2}$
Where u is the initial velocity
v is the final velocity
a is the acceleration
s is the displacement
t is the time
Note down the given parameters from the question.
Step 2 :
To find out the final velocity, use the below kinematics equations
v=u+at
s=ut+$\frac{at^{2}}{2}$
Calculate the final velocity and displacement of an object at 5s whose initial velocity is 30m/s moving with an acceleration of 3m/s2?
Step 1 :The given measurements are,
u=30m/s, v=?, s=?, a=3m/s2, t=5s
Step 2 :The kinematics equations for final velocity ans displacement is given by,
v=u+at
s=ut+$\frac{at^{2}}{2}$
v=30+3×5=30+15=45m/s
S=30×5+$\frac{3×5^{2}}{2}$
s=150+$\frac{75}{2}$
s=150+37.5=187.5m
Answer :Final velocity, v=45m/s
Displacement, s=187.5m
Determine the displacement and final velocity at 10s of a moving body whose initial velocity is 20m/s moving with an acceleration of 5m/s2?
Step 1 :The given measurements are,
u=20m/s, v=?, s=?, a=5m/s2, t=10s
Step 2 :The kinematics equations for final velocity ans displacement is given by,
v=u+at
s=ut+$\frac{at^{2}}{2}$
v=20+5×10=20+50=70m/s
S=20×10+$\frac{5×10^{2}}{2}$
s=200+$\frac{500}{2}$
s=200+250=450m
Answer :Final velocity, v=70m/s
Displacement, s=450m
