A soccer player kicks a soccer ball (m = 0.42 kg) accelerating from rest to 32.5m/s in 0.21s. Determine the force that sends soccer ball towards the goal. Help:(

65 N

Explanation:

m = Mass of ball = 0.42 kg

u = Initial velocity = 0

v = Final velocity = 32.5 m/s

a = Acceleration =

t = Time = 0.21 s

Force is given by

The force that sends soccer ball towards the goal is 65 N.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
