Jake drags a sled of mass 25 kg across the snow. the sled is attached to a rope that pulls with a force of 50 n at an angle of 32 degrees. if there is no friction, what is the normal force acting on the sled?

218.5 N

Explanation:

In order for the sled to be in equilibrium along the vertical direction, the forces acting along this direction must be balanced. So the equilibrium equation is:

where

N is the normal force

F = 50 N is the force that pulls the sled

is the angle between the force and the horizontal, so

is the component of F acting along the vertical direction

(mg) is the weight of the sled, with

m = 25 kg being the mass of the sled

g = 9.8 m/s^2 is the acceleration due to gravity

Solving the formula for N, we find

v=ir = 3x15 =45 v

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
