Question 1 Report
Make t the subject of formula \(S = ut + \frac{1}{2}at^2\)
Answer Details
Given S = ut + 12at2 1 2 a t 2 S = ut + 12at2 1 2 a t 2 ∴ 2S = 2ut + at2 = at2 + 2ut - 2s = 0 t = −2u±4u2+2as2a − 2 u ± 4 u 2 + 2 a s 2 a = -2u π π √u24u2+2as2a u 2 4 u 2 + 2 a s 2 a
= 1a 1 a (-u + √U2−2as U 2 − 2 a s )
