I push down on a 270kg crate with a force of 450N at 25 degree angle. If the crate is 15m away 10. seconds later, what is the mu of kinetic friction?

Sorry my friend i don't know the answer. i am just in 6th

I’m not sure about this question

34 degrees fahrenheit

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
