Juan Deroff drops his Twinkie out of his second story bedroom window. If it takes
1.5 seconds to hit the ground, how fast will it be going? (Hint: The acceleration due to gravity is 9.8
m/s2.)

answer: good job it's all correct !

explanation:

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

the ima (higher than 1m) will be greater than the ima with the height of 1m.
