Object a with a mass of 500 kilograms hits stationary object b with a mass of 920 kilograms. if the collision is elastic, what happens after the collision?

Both objects will move

Explanation:

The collision is elastic, which means that both the total momentum and the total kinetic energy will be conserved after the collision. Therefore, we will have:

where the first equation represents the conservation of the total momentum, while the second equation represents the conservation of the kinetic energy, and

is the velocity of object A before the collision

is the velocity of object A after the collision

is the velocity of object B after the collision

are the masses of the two objects.

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
