if my cross is 3 3/8 inches tall and 2 1/2 inches wide how wide should it be if its 7 1/2 inches tall
[((cotx)^(1/3))((csc^4(x))] i dont understand how to integrate the first part because it should be either even or odd, but this is neither.. help!
integral of cscx^(2/3)(cot^3)x i know that cot^2x is csc^2(x)-1, but i just don't understand how to solve the cscx^(2/3), any help? i also know that its trig integrals/substitution...

A falling rubber ball of mass m hits the ground with a speed of v and bounces straight up again after a 20% speed loss during the collision. The magnitude of the impulse it receives from the ground is A 0.2mv B 0.8mv C mv D 1.8mv
The minute hand of a bedside clock is 2.5 cm long. In order for the clock to keep proper time, the minute hand should maintain an average angular velocity of
A rectangular plank with mass m kilograms measures x metres wide by y metres high. It is clamped at its very left edge, one third of the way down from the top, as shown. To keep the plank level, the clamp must exert a torque of
A heavy steel ball S is suspended by a string from a block of wood W, as shown in the sketch. The entire system is dropped from a height. Neglecting air resistance, the tension in the string is equal to A zero B the weight of S C the difference of the masses of S and W D the d...
An unknown mass is suspended by a string from one end of an uniform stick which has a mass of 120 g. In order to balance the stick, it must be supported one third of its length away from the mass. the unknown mass is therefore?
