Answer:
20 m/s
Explanation:
First, we calculate for the acceleration down the incline using .
a = (9.80)sin(20°)
a = 3.35
Then, we use one of the kinematics equations, .
= 0 m/s
a = 3.35
= 62 m
Answer:
20 rad/s^{2}
Explanation:
weight / force (F) = 150 N
radius (r) = 0.5 m
mass (m) = 15 kg
angular acceleration = tangential acceleration / radius
where
- tangential acceleration = force/ mass = 150/15 = 10 m/s^{2}
- substituting the above into the equation for angular acceleration we have
angular acceleration = 10 / 0.5 =
