A 3000 kg truck moving with a velocity of 15 m/s hits a 1000 kg parked car. The impact causes the 1000-kg car to be set in motion at 20 m/s. What is the velocity of the truck after the collision?

from

explanation:

wind is defined by the direction it blows from.   for example, a wind blowing from north to south is called a northerly wind.

attach the statements so i can answer : )

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
