Two forces of intensities 3 N and 4 N act simultaneously on a body. If these forces have the same direction and sense, what is the intensity of the resulting force?

If the two forces applied to an object act in the same direction ,then the resultant force acting on the object is equal to the sum of two forces: When two forces act in the same direction their effective magnitude increases

Explanation:

powerful computers now, not then

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
