If a 3 kg object is falling at terminal velocity, what upward force of air resistance does it experience?

Which quantities are scalars? choose all that apply a.distance b.speed c. acceleration d.velocity

The position of a crate sliding down a ramp is given by x=(0.05t^3) m, y=(1.7t^2) m, z=(6−0.85t^5/2) m, where t is in seconds. (a) determine the magnitude of the crate's velocity when t = 2 s. (b) determine the magnitude of the crate's acceleration when t = 2 s.
