What is the combined thickness of these five shims? 0.008, 0.125, 0.15, 0.185, and 0.005 cm?

Hint: The phrase combined thickness tells us that we need to add these five decimals to get their sum.

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
