Problem: An object m slides in a circle of radius r=1.2m on a frictionless table while attached to a hanging block m which has a mass of 1.8kg by a cord through a hole in the table. If the speed of m is 4.3m/s,
Part A: What is the mass of the object m?
I need help to find the mass of the object.
An object falls because of gravity at the rate of -920 cm/s2 (- sign is indicative of a downward direction) for 10.00 Seconds. If it starts from rest (vo = 0) and its position starts from do= 0.0, where is it 10.00 Seconds later.
