Abox with a mass of 70 kg sits on a slope of 40 degrees. you are tasked with pushing the box up the slope. the static (stationary) coefficient of friction between the box and the slope is 0.55, and the kinematic (while moving) coefficient of friction is 0.35. a. what is the minimum force required to keep the box from slipping? b. what is the minimum force required to begin pushing the box up the slope? c. what is the minimum force required to maintain the box moving up the slope? d. what is the force required to accelerate the box up the slope at 0.65 m/s2 once it is already moving upwards? give your answers in newtons (n).

PART a)

Force of friction on the box is given by formula

now the component of weight along the inclined

now by force balance the force required to hold the block

Part b)

to slide the block upwards the friction force will be upwards along the plane

Part c)

Kinetic friction on the block is given by

now in order to move it up

Part d)

now to accelerate upwards by 0.65 m/s^2 we can use

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
