Answer:
The acceleration of the toboggan going up and down the hill is 8.85 m/s² and 3.74 m/s².
Explanation:
Given that,
Speed = 11.7 m/s
Coefficients of static friction = 0.48
Coefficients of kinetic friction = 0.34
Angle = 40.0°
(a). When the toboggan moves up hill, then
We need to calculate the acceleration
Using formula of acceleration

Put the value into the formula


(b). When the toboggan moves up hill, then
We need to calculate the acceleration
Using formula of acceleration

Put the value into the formula


Hence, The acceleration of the toboggan going up and down the hill is 8.85 m/s² and 3.74 m/s².
