A particle has constant acceleration k m,s-2, initial velocity -2 m,s-1, and initial displacement 3

Question

A particle has constant acceleration k m,s-2, initial velocity -2 m,s-1, and initial displacement 3 m. Its displacement at t=2 seconds is 7 m. Find k and its least displacement for t 0.

Accepted Answer

$k=4$; least displacement $\dfrac{5}{2}$ m at $t=\dfrac{1}{2}$ s.
