Answer:
minimum angle is 128.69°
Explanation:
given data
player velocity with respect ground v1 = 3.5 m/s
ball velocity with respect himself v2 = 5.6 m/s
to find out
smallest angle
solution
we know ball velocity with respect field will be
ball velocity = v1 +v2
ball velocity = 3.5 + 5.6 = 9.1m/s
we consider angle that player hit ball is θ
then by as per figure triangle
cosθ =
cosθ =
θ = 51.31
so minimum angle is 180 - 51.31 = 128.69°

Explanation:
Formula for magnetic force acting on current carrying cable:
Where I = 345A is the current in the wire, B = is the magnetic magnitude generated by Earth. L = 46.9 m is the cable length.
is the angle between vector B and cable direction.
