Aman is dragging a trunk up the loading ramp of a movers truck. the ramp has a slope angle of 20.0°, and the man pulls upward with a force → f f→ whose direction makes an angle of 30.0° with the ramp. how large a force → f f→ is necessary for the component fx parallel to the ramp to be 90.0 n

103.92 N

Explanation:

Given

Ramp angle

Force required to create

Let the Force be F

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
