a car enters the interstate moving at 80.0km/hr. The driver acceleration uniformly and after 2.1 minutes the car has a velocity of 120. km/hr . What is the average acceleration in km/hr^2

6 cos 34, 6 sin 34 trig

where is the photo and the answer choices?

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
