i have this question
a crane is raising a steel beam (350 kg) the max tension the supporting cable can take without breaking is 7000 Newtons
a) is it safe to life the beam at a constant speed of 3m/s? prove answer
(the only idea i have is the use of f=ma, but then i am stuck w/acceleration when i need to use speed i just don't know what to do.)
