A car with a mass of 1375 kg is moving 7.5 m/s [N34E] and collides with another car with a mass of 1700 kg moving 4.5 m/s [S]. The two cars stick together when they collide.
What is the final velocity of both vehicles?

the results is a decrease in air temperature with an increase of altitude.

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

i think it would be 5
