got the first 2. Still need number 3 and this:
A fire helicopter carries a 561 kg bucket of water at the end of a 24.9 m long cable. Flying back from a fire at a constant speed of 43.6 m/s, the cable makes an angle of 48.4° with respect to the vertical. Determine the force of air resistance on the bucket.
Vectors are your friends. change the weight and speed into force
and this:
A 2016-kg elevator moves with an upward acceleration of 1.86 m/s2. What is the tension in the cable that supports the elevator?
f= m x a equal but opposite force is tension dont forget to get the acceleration of gravity force either you need both
