Explanation:
Acceleration. Angular acceleration: Is the rate of change of the angular velocity of a body with respect to time.
Force. Torque: Is also called rotational force, since an applied torque will change the rotational motion of a body.
Mass. Moment of inertia: It is the resistance that opposes a body to rotates.
Work. Work: In a rotational motion, the work is done by the torque.
Translational kinetic energy. Rotational kinetic energy: is the kinetic energy due to the rotational motion of a body.
Linear momentum. Angular momentum: Represents the quantity of rotational motion of a body.
Impulse. Angular impulse: Is the change in angular momentum of a body.
Answer:
t = 25 seconds
Explanation:
Given that,
Distance, d = 115 m
Initial speed, u = 4.2 m/s
Final speed, v = 5 m/s
We need to find the time taken in increasing the speed.
We know that,
Acceleration, 
....(1)
The third equation of kinematics is as follows :
Hence, it will take 25 seconds to increase the speed.
Answer:
Mechanical energy is the sum of the potential and kinetic energies in a system. The principle of the conservation of mechanical energy states that the total mechanical energy in a system remains constant as long as the only forces acting are conservative forces.
Explanation:
Answer:
It works by testing the ph levels in those areas it is placed in.
Explanation:
Buscar nuevos amigos, si no te quieren contigo o te ponen de lado, en realidad no son tus amigos o compañeros, nadie se merece eso, no necesitas esas personas en tu vida.
