An objects speed is 2.40 m/s and its momentum is 120.0 kg m/s. what is the mass of the object?

Momentum = mass X Velocity
Using logic we can see that the velocity would be positive so 2.40 doesn't change.
120/2.40 = 50kg
Mass of object is 50 kg.
Hope that helps! :)

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.
