A radar tower sends out a signal at an angle of 41.0∘ above the horizontal. The signal reflects off of a plane and returns to the transmitter in a total time of 7.50 μs. Determine the height of the plane.

![As shown in the diagram above, a block of mass m slides down a plane inclined at an angle of theta = θ above horizontal. The coefficient of static friction between the block and the plane is mus = μs. The coefficient of kinetic friction between the block and the plane is muk = μk. The block is sliding down the plane. The magnitude of the friction force that the block exerts on the plane must be equal to which of the following? Choose all that apply. More than one answer may be correct. μsmgsin(θ)[ that says musmgsin( theta )] μsmgcos(θ) [ that says musmgcos( theta) ] mgsin(θ) [ that says mgsin( theta) ] mgcos(θ) [ that says mgcos( theta)] μkmgcos(θ) [ that says mukmgcos( theta) ] μkmgsin(θ) [ that says mukmgsin( theta) ]](https://www.doubtrix.com/uploads/editor/1164956651PrYwaExjUW.png)
