Leviafan [203]

Answer: 29.83m

Explanation: coefficient of friction= v^2/rg

Coefficient of friction=0.27

V=32km/h

Convert km/h to m/s

32*1000/3600

32000/3600=8.89m/s

0.27=8.89^2/r*9.81

0.27*9.81*r=79.0321

R= 79.0321/2.6487

R=29.83m

A bus with a vertical wind shield moves horizontally

Katena32 [7]

Answer:

(3) 53°

Explanation:

We want to measure the angle that the rains form with the vertical wind shield, so we have to measure the angle relative to the vertical. This means that we can write the following equation

$tan \theta = \frac{v_x}{v_y}$
