Question

a particle moves with a constant acceleration in a straight line at t=10sec the velocity&displacement are 16m/s and39 m respectively.what will be its velocity after 10s

Answer 1

at 10th second,
s=u+a(t-1)
39=16+a*9
=>a=13/9 m/s²
now, s=ut+0.5*at²
s=232.22m
v²=u²+2as
v²=926.857
=>v=30.444 m/s
