A hollow sphere with a mass of M 4 kg and radius of 30 cm is rolling down an inclined surface (hill) with inclined angle of 37 degrees, from a height of 2 meters. 1. Find its rotational inertia. 2. Find its linear AND angular acceleration down the hill. 3. Find its linear AND angular velocity at the bottom of the hill. 4. Find the linear AND rotational kinetic energy at the bottom of the hill. 5. Find the frictional coefficient of the inclined surface, if the sphere is making pure rolling motion. 6. Find the number of revolutions the sphere rolls over along the inclined. (Convert rad to rev) You are given a "Gold Crown" to determine whether it is made of pure Gold or not. It has a mass of 675 grams when it is weighed in the air. Then it is submerged in oil (with density of 957 kg/m^3), it reads 640 grams. 7. Find the density of the Crown. Compare to the Gold

Please answer A, B, and C.

You walk 200 feet west and 100 feet north to bury your treasure chest. But when you return to dig it up, you will be in a hurry and should walk straight to it. Determine the angle you should walk, relative to due west and the distance.

Vector a is 37m on x axis. Vector b 36 m @230 degree to x axis . Vector c 12 m @ 140 degree x axis. deternine x and y components of vector a,b , and c separately

A spelunker is surveying a cave. She follows a passage 160 m straight west, then 230 m in a direction 45degree east of south, and then 280 m at 30 degree east of north. After a fourth unmeasured displacement, she finds herself back where she started.

2 sig figs. Answer in degrees. Put north in the direction of positive y, and East in the direction of positive x.

Given vector A=2i-3j and vector B = 2i -4j. If vector C = A -2*B then C equals ..

2.12 A chimpanzee sitting against his favourite tree gets up and walks 51 m due east and 39 m due south to reach a termite mound, where he eats lunch. (a) What is the shortest distance between the tree and the termite mound? (b) What angle does the shortest distance make with respect to due east?

A person walks first 10 km north and 20 km east then the resultant distance is

A vector A is added to B=6i-8j. The resultant vecor is in the positive x direction and has a magnitude equal to A. What is the magnitude of A?
