A body explodes and splits into three pieces, the first piece has mass of 1.25kg and velocity of [ 30 -10 ]m/s, the second piece has main of 3.25kg and velocity of [ -17 10 ]m/s the third piece has velocity of [ 35.5 40 ]m/s. What is the mass of the third piece. What was the total mass of the body before the explosion.

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?

How much force was applied to an object if was moved 2 meters and the work done on the object was 8 joules? a. 0.25 n b. 4 n c. 6 n d. 16 n

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?
