Two objects "A" and "B" are such that body A is rotating with uniform angular speed of 2rad s-1 while B with uniform acceleration of 2rad s-1. If the ratio of their moment of inertia IA:IB= 2:1, then what is the ratio of torque A and torque B?? a)2:1 B)zero C)1:2 D)infinity

Ais not a compound machine. a. bolt b. shovel c. handcart (dolly) d. see-saw (teeter totter)

An object moves from the position +34m to the position -15m in 15 seconds. what is it's total displacement? what is it's average velocity?

Astone is dropped with no initial velocity from the top of a cliff and hits the ground a time of 3.9 s later. what is the height of the cliff, in units of meters? you may assume that air resistance is negligible. give the answer as a positive number question 15 a figure skater is rotating at a rate of 200 revolutions per minute. what is the angular speed, in units of rad/s? 200 o 20.9 12000 o 3.33
