1. The problem statement, all variables and given/known data A load of 200kg is lifted through 50m by a vertical cable. The load accelerates uniformly from rest for 20 seconds, travels at constant speed for 10 seconds then decelerates to rest in a further 10 seconds. Find the maximum speed attained and the tension in the cable at each stage. 2. Relevant equations F=ma and maybe some SUVAT ones? 3. The attempt at a solution I started using F=ma so that for the first stage I got T=200a+1960 but soon after that I got a bit confused. Help would be really appreciated because I'm stuck! Thanks!
