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)

Explanation:

Given

mass of archer

Average force

extension in arrow

Work done to stretch the bow with arrow

This work done is converted into kinetic Energy of arrow

where v= velocity of arrow

(b)if arrow is thrown vertically upward then this energy is converted to Potential energy

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

1 - wave length

2 - amplitude

3 - crest

4 - trough
