A cannonball with mass m is fired with an initial speed V0 at an angle theta ablve the horizontal. Compute the time it will take the ball to reach its maximum height, and compute this maximum height, in terms of V0, theta, and g. Note that when the ball's height reaches a maximum, its speed in the vertical direction will be zero.
A 4 m diameter sphere is embedded in insulation. The sphere contains a liquid-ice mixture maintained at 0 deg C. The ambient temperature surrounding the insulation is 25 deg C.
The weight W causes a tension of 100lb in cable CD. If d= 2ft, what is the momentum about the z axis due to the force exerted by the cable CD at point C?
The direction of the forces are 0,-30 and +120 degrees from the positive X axis. Determine the magnitude and direction of the resultant force.
Determine the molecular weight of a poly(ethylene-propylene) with a degree of polymerization of 25,000 given that 20% of the mers (by number) are ethylene and 80% are propylenel.
a man of mass m1 walks along a plank of length l with a constant acceleration a relative to the plank. The mass of the plank is m2 and the coefficient of friction between the plank and the ground is mu. Find the distance the plank moves if the man..
If the deflection of the gae fluid height, h, is 2 inches find the 1) velocity of the jet air and 2) the force exerted on the disk by the air.
