A force represented as show in figure acts on a body having a mass of 16 kg. The velocity of the body at =10 s, if the body starts from rest:- (A) 100 m/s (B) 50 m/s (C) 49 m/s (D) 39 m/s

Tardigrade Admin · Accepted Answer

Area under ( F - t ) curve = M ( v f - v i ) or 50 × 5+75 × 5=16( v f -0) ∴ v f =39 m / s

Q. A force represented as show in figure acts on a body having a mass of $16 k g$ . The velocity of the body at $= 10 s$ , if the body starts from rest:-

100 m/s

50 m/s

49 m/s

39 m/s

Area under $(F - t)$ curve $= M (v_{f} - v_{i})$
or $50 \times 5 + 75 \times 5 = 16 (v_{f} - 0)$
$∴ v_{f} = 39 m / s$
