A rocket rises vertically from rest, with an acceleration of 3.2 m/s2until it runs out of fuel at an altitude of 1200m. After this point, its acceleration is that gravity in a downward direction. a. How long does it take for the rocket to run out of fuel?b. What is the rocket’s velocity when it reaches this point?c. How much total time does it take to reach maximum altitude?18 Worksheet Problems:d. What maximum altitude does the rocket reach?e. How much total time is it in the air?f. With what velocity does it strike the Earth?

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
