Question

Please help me with this 3 part problem using algebra based physics

A heavy box with a mass of 12 kg is resting on a surface
inclined at 35 degrees above the horizontal. The coefficient of
static friction between the box and ramp is µs = 0.8.
35°
a.) How large is the normal force acting on the box?
a.) 118 N
b.) 96 N
c.) 77 N
d.) 67 N
b.) How large is the static friction force holding the box in place?
a.) 118 N
b.) 96 N
c.) 77 N
d.) 67 N
c.) Fed up with life on this planet, I develop a "Fargate" that allows instantaneous travel to other
worlds. The first planet I arrive on has a radius half that of the Earth, and half the Earth's mass.
What acceleration due to gravity will I feel on the surface of my new home, compared to my usual
g = 9.8 m/s??
a.) Less than on Earth: One-half of g
b.) The same as on Earth: One g
c.) More than on Earth: Two times g
d.) Much more than on Earth: Eight times g
