The speed at t = 1 second is 54.28 meters per second.
Here we know that the speed of the arrow is 58 m/s, and the height is given by the function:
y = 58*t - 1.86*t^2
If we want to find the speed, we need to differentiate with respect to t, so we will get:
v(t) = 58 - 2*1.86*t
v(t) = 58 - 3.72*t
To get the speed when t = 1, we just need to evaluate the function v(t) in t = 1, we will get:
v(1)= 58 - 3.72*1 = 54.28
This means that the speed at t = 1 second is 54.28 meters per second.
