Question

the rectilinear motion of a paricle is governed by a=-8s2 where a is in m/s2 and v is in m/s when 10 t=2 sec,v=10m/s and s=91m determine the value of s at t=3 sec

Answer 1

Answer:

As area under acceleration time graph gives velocity

so velocity= 1/2 x base x height = 1/2x12x10 = 60 m/s
