A body moves in a straight line with uniform acceleration of 2 m/s2. If the initial
velocity of the body is 16 m/s, find its final velocity after covering 36 m of
distance using the third equation of motion.
O a) v = 10 m/s
Ob) v = 15 m/s
O c) v = 6 m/s
O d) v = 20 m/s

Answer:
v =20
Explanation:
Here we have
acceleration =2m/s^2. (please note that' ^ 'refers to the power)
initial velocity=16m/s
distance =36m
using
v^2=u^2+2as
where v =final velocity
u =initial velocity
a = acceleration
s = distance (or displacement)
v^2 = (16)^2 +(2)(2)(36)
