I am having trouble understating which equation to use.

Suppose the force of air resistance is proportional to the speed of the object and in the direction opposite the object's velocity. If you throw an object upward, when is the magnitude of the object's acceleration highest? A. It is highest at the top of its trajectory. B The acceleration of the object is the same throughout the entire trajectory. No answer text provided. It is highest right after the object is released.

Plz use g = 9.8 m/s2

10. If two objects are dropped in an environment without air resistance, what will occur? Both of the objects will fall with constant velocity O The lighter of the two objects will fall faster than the heavier. O The heavier of the two objects will fall faster than the lighter. O The objects will accelerate downward at the same rate.

How do I know if this object can remain at rest? Please explain step-by-step.

An elevator loaded with tourists has a mass of 1750 kg. a.) The elevator accelerates upward (in the positive direction) from rest at a rate of 1.55 m/s2 for 2.3 s. Calculate the tension in the cable supporting the elevator in newtons b.) The elevator continues upward at constant velocity for 8.5 s. What is the tension in the cable, in Newtons, during this time? The elevator experiences a negative acceleration at a rate of 0.65 m/s2 for 2.6 s. What is the tension in the cable, in Newtons, during this period of negative accleration? c.) How far, in meters, has the elevator moved above its original starting point?
