A large crate with mass m rests on a horizontal floor. The coefficients of friction between the crate and the floor are μs and μk. A woman pushes downward with a force F⃗ on the crate at an angle θ below the horizontal. (a) What magnitude of force F⃗ is required to keep the crate moving at constant velocity? (b) If μs is greater than some critical value, the woman cannot start the crate moving no matter how hard she pushes. Calculate this critical value of μs.

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

the answer is b, have negligible mass
