Answer:
Distance d=8.63m
Explanation:
mass of object m=47.5 kg
Initial velocity vi=0 m/s
Magnitude of force on object F(t)=(17.0 N/s)t
To find
Distance
Solution
The rocket accelerates due to variable force so we apply Newtons second law but the acceleration will not be constant because the force is not constant
We use ax=Fx/m to find acceleration but it must be integrate to find velocity and then the distance that rocket travels
So
Distance d=8.63m
Answer:
The net force is 392N, pointing down.
Explanation:
The net force is the sum of all forces acting on the rock, namely the gravity ("+" acting downward) and the friction force due to air resistance ("-" acting upward):
The net force is 392N and pointing down (positive)/
Answer:
Explanation:
The relationship between angular acceleration α and torque τ is given by :
Here,
is the moment of inertia. It depends on the mass and the distance from the axis of rotation.
is the angular acceleration
Hence, this is the required solution.
