u=18 km/h = 18/3600 * 1000 = 5 m/s
u = 5mps
a = 2mpsE2
t = 5s
According to first equation of motion,
v = u + at = 5 + (2)(5) = 5 + 10 = 25 mps
Hence, final velocity = 25 m/s
u = 5mps
a = 2mpsE2
t = 5s
According to first equation of motion,
v = u + at = 5 + (2)(5) = 5 + 10 = 25 mps
Hence, final velocity = 25 m/s
