A hiker walks 34 cm from her base camp at 67 degrees with respect to the x axis. The next day she walks 93 cm in a direction 28 degrees with the respect to the axes and discovers a pond. Find the magnitude and direction of her resultant displacement between the base camp and the pond.

trig 15.3 cos

the closer the planet is to the sun, the larger the gravity

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
