A student who is 1.5m tall shoots a 0.03 kg dart out of a blow gun horizontally. The dart lands 7.3m away. A) How fast did the dart leave from the blow gun?
B) If the dart took 0.21s to exit out of the blow gun while it was being shot out, with what average force did the boy blow into
the gun?

When using the scientist method, which step comes last?

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
