QuestionA motorbike accelerates from rest to 12 m/s in 3 seconds on a level road. If the force is 3000 Newton, what is the total mass of the cyclist and the motorbike?Community AnswerWe know that F = ΔQ/Δt, so let's go from there. We also know that F = 3000 N, v = 12 m/s, and Δt = 3 s. So what we have is 3000 = ΔQ/3. ΔQ = Q2 - Q1 and Q = mv. So Q1 = 0, because the motorbike accelerates from rest (v1 = 0), and Q2 = 12m. ΔQ = 12m - 0 = 12m. We now have 3000 = 12m/3, 3000 = 4m, m = 750 Kg.

QuestionHow do I find out mass? Is it measured by newtons?Community AnswerNo, mass is not measured in newtons. Weight is measured in newtons, because it is a force that is acting on the body. The units that describe mass are grams and kilograms, with kilograms being the S.I unit. You can use the formula f=ma to find mass with a formula.
