Aforce of 450 n accelerates a box across a frictionless surface at a rate of 15 m/s 2 . what is the mass of the box? 30 n 30 kg 6,750 n 6,750 kg

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
