Question

The distance, s, travelled by a motorcycle varies directly with the square of speed, v, and inversely with acceleration, a. Given that s = 1000m, v = 20ms⁻¹ and a = 0.2ms⁻².
Calculate the value of a when s = 1500m and v = 25ms⁻¹.
Jarak, s, yang dilalui oleh sebuah motosikal serubah secara langsung dengan kuasa dua laju, v, dan secara songsang dengan pecutan, a. Diberi bahawa s = 1000m, v = 20ms⁻¹ dan a = 0.2ms⁻².
Hitung nilai a apabila s = 1500m dan v = 25ms⁻¹.
