Question

The acceleration of a particle varies as
$a = 3 {t}^{2} + 2t + 1 \: m {s}^{ - 2}$
Find displacement of the particle after 2 seconds of start.​

Answer 1

Answer:

34m

Explanation:

s=ut + 1/2at²

here assuming that the particle starts from rest u=0

given,t=2secs

hence,

s=0×2 + 1/2 ×(3×4 + 2×2 + 1) × 4

=34m
