We will apply the concept related to the current change given in the same problem. We will divide both currents into two states: the new current and the old current. As the current is the change of the load in a certain time, we will have that the old current is,
If it takes 5 times more time, then we will have the new current is,
Replacing the given value of the old current we will have to,
Therefore the new current will be the old current.
r = (x, y) + (6.5*cos(18°)-x, 6.5*sin(18°)-1)
v1= (x, y), v2=(6.5*cos18°-1, 6.5*sin18°-1)
You can choose any real numbers for x and y. See attached for a little more depth.
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°
