A 4-kg block and a 2-kg block can move on the horizontal frictionless surface. The blocks are accelerated by a 12-N force that pushes the larger block against the smaller one. Determine the force that the 2-kg block exerts on the 4-kg block.

Matt is driving down 7th street. he drives 150 meters in 18 sec. assuming he doesn’t slow down or speed up, what is his speed?

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
