The data arranged below in the form of a table was obtained for a motor cyclist of total mass 120kg traveling from Sun city towards Delta state. velocity/ms^(−1) 00 20 40 50 50 60 70 85 time,t/s 00 5 10 12 20 35 40 45 i) plot a graph of velocity(y−axis) against time(x−axis) ii) Detemine the acceleration of the cyclist for the first part of the motion iii) Calculate the pull of the engine during the first 12.5s if this section of the road is horizontal and friction with all other forces is negligible. iv)what is the momentum change during the first 12.5^(th) second v) detemine the kinetic energy of the cyclist at the 37.5^(th) second vi) for how long is the resultant force zero on the cyclist during motion?
