Awar wolf is a device used during the middle ages to assault fortifications with large rocks. a simple trebuchet is constructed with a large, stiff 4.1 m rod (assume it has negligible mass) with a heavy object of mass 52 kg and 14 cm from the axle around which the device pivots and a cup on the far end that holds the rock. the war wolf is loaded when it is in a horizontal position, and the rock is projected horizontally when after it has rotated to a vertical position. if the rock has a mass of 123 g, how fast (linear speed) does it move when launched?

v=41.23 m/s

Explanation:

Given

mass of heavy object

distance of from the axle

mass of rock

Length of rod

distance of from axle

Net torque acting is

Work done by is converted to rock kinetic Energy

thus

Where

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
