A constant horizontal force of 10 lb rests on a body of smooth horizontal plane. The body starts from rest and is observed to move 250 ft in 5s.
a). What is the mass of the body?
b). If the force ceases to act at the end of 5s, how far will the body move in the next 5s?
A hollow sphere 6 in inside diameter is rotated on a cable at 100 rpm. If the cable is 6 ft long and makes an angle of 30 degrees with the horizontal, what is the pressure in the center of the sphere if it is full of water? what is the equivalent specific weight at that point?

A flanged bolt coupling consists of two concentric bolt circles. One bolt circle consists of six 0.5-in-diameter steel bolts on a circle 9 inches in diameter and the other consists of eight 0.5-in-diameter steel bolts on a circle 12 inches in diameter. What is the shearing stress in the bolts if a torque of 7 kip-ft is to be carried by the assembly?
Please upload more examples and answers on Dynamics sirs maam Thanks in advance
Please hep me to obtain the general solution
xdy-[y+xy3(1+lnx)]dx=0
v((2v^2) u -3) du + (3u^2) (v^2) - 3u + 4v) dv = 0
