An electric pole shown in the figure below supports a power line that passes through it. A cable tied to the pole at B passes through a hole in the struct at C and is then tied to the ground at B. There is no friction between the struct and cable. What is the force exerted by the cable onto the pole at B, if the tension in the cable is 47lb.

Iwould sure like to answer your question but i honestly just don’t know

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

Look it up you feel me
