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.
