A cyclist and cycle have a combined mass of 78 kg as they accelerate along a race track at 2.5 m/s2. Calculate the fore exerted as they accelerate. ( F= 195 N ) I solved this , but I do not know other one, which is :
A lift of mass 400 kg is accelerated upwards at 2 m/s2. calculate the force in the rope pulling.
Please help me. Many thanks
