A ball A is thrown vertically upward from the top of a 21-m-high building with an initial velocity of 7 m/s. At the same instant another ball B is thrown upward from the ground with an initial velocity of 25 m/s Part B Determine the time at which they pass. Express your answer to three significant figures and include the appropriate units HA ? Value Units t =

Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Packages are thrown down an incline at A with a velocity of 2.5 m/s. The packages slide along the surface ABC to a conveyor belt which moves with a velocity of 2 m/s. The distance d= 7.5 m and μk = 0.25 between the packages and all surfaces. 2 m/s 7 m B 30° JAM'S Determine the speed of the package at C. (You must provide an answer before moving to the next part.) m/s. The speed of the package at Cis
