1how many grams of copper are required to make a hollow spherical shell with an inner radius of 5.7cmand outer radius
of 5.75cm



the densityof copper is 8.93g /cm3
.....
2-the period T of a simole pendulm is measured in time units and given by T=2π√1/g,where 1 is the acceleration due to gravity in units of length
divided by the square of time.show that this equation is dimensionally correct
....
3-A 5.00-kg object placed on a frictionless,horizontal table is connected to a string that passes over a pulley ad then is fastened to a hanging 9.00-kg
object, as in figure.find the acceleration of the two object and the tension in the string
.......
4- tow blocks of masses m1andm2,with m1>m2 are placed in contact with each other on a frictionless,horizontal surface, the systemas in figure.A constant
horizontal force F is applied to m1 as shown.
(a) find the magnitude of the acceleration of the system
(b)determine the magnitude of the contact force between the two blocks
........
5-A woman weighs 120 1b. determine(a)her weight in newtons (N)and (B) her mass in kilograms (kg
........
6-If a man weight 900 N on the earth, what would he weigh on jupiter, where the acceleration due to gravity is 25.9m/sec

..........
7- An object of mass M is held in place by an applied force F and A pulley system as shown in figure. the pulleys are massless and frictionless. find
(A)the tension in each section of rope,t1,t2.t3,t4 and t5 and(B)the magnitude of F

.........
8-two object are connected by a light string passing over a light frictionless pulley asshown in figure. the object of mass 5.00 kg
is released from rest. using the principle of conservation of energy,(A)determine the speed of the 3.00-kg object just as the 5.00-kg object hits the ground.
(B)find the maximum height to which the 3.00-kg object rises.
