An archer puts a 0.30 kg arrow to the bowstring. an average force of 201 n is exerted to draw the string back 1.3 m. a. assuming that all the energy goes into the arrow, with what speed does the arrow leave the bow? (41.7 m/s)b. if the arrow is shot straight up, how high does it rise? (88.9 m)

Six pendulums of mass mand length las shown are released from rest at the same angle theta from vertical. rank the pendulums according to the numberof complete cycles of motion each pendulum goes through perminute. a. l= 1m m=2kg b. l= 4m m=1 kg c. l= 2 m m= 2 kg d. l= 1 m m= 4 kg e. l= 2 m m = 4 kg f. l= 4m m = 4kg
