The power exerted by the cyclist is determined as 50 W.
<h3>
Average power exerted by the cyclist</h3>
The power exerted by the cyclist is calculated as follows;
P = FV
where;
- F is the applied force
- V is velocity
P = 20 x 2.5
P = 50 W
Thus, the power exerted by the cyclist is determined as 50 W.

#SPJ1
The angle between the string and the vertical is computed by:
Centripetal acceleration Ac = V²/R = 18²/75 = 4.32 m/s² horizontal
Gravitational acceleration g = 9.8 m/s² down
Θ = arctan(Ac/g)
= arctan (4.32m/s^2 / 9.8 m/s^2)
= 23.79° is the answer.
