A marble is rolling at a speed of 3.31 m/s  Falls of the end of the table that is 91.2 cm tall.  how long will the marvel be in the air?

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s

Work = force × a. work b. energy c. distance d. momentum

For which pair of objects would adding the same a
