Answer:
the velocity is zero, the acceleration is directed downward, and the force of gravity acting on the ball is directed downward
Explanation:
Is this exercise in kinematics
v = v₀ - g t
where g is the acceleration of the ball, which is created by the attraction of the ball to the Earth.
At the highest point
velocity must be zero.
The acceleration depends on the Earth therefore it is constant at this point and with a downward direction.
The force of the earth on the ball is towards the center of the Earth, that is, down
all other alternatives are wrong
Answer:
59.503987 seconds
Explanation:
b = Proportionality constant = 50 Ns/m
g = Acceleration due to gravity = 9.81 m/s²
m = Mass of object = 700 kg
We have the equation of velocity
The equation of motion
when x(t)=2000
The time taken is 59.503987 seconds

Answer;
The dual mass flywheel
The dual mass flywheel has a center support bearing that carries the load between the inner and the outer flywheel and is fitted with damper springs to absorb shocks.
Explanation;
The dual mass flywheel eliminates excessive transmission gear rattle, reduces gear change/shift effort, and increases fuel economy. There are two basic types of Dual Mass Flywheels. The first is made up of a primary and secondary flywheel with a series of torsion springs and cushions.
-There is a friction ring located between the inner and outer flywheel that allows the inner and outer flywheel to slip. This feature is designed to alleviate any damage to the transmission when torque loads exceed the vehicle rating of the transmission. The friction ring is the weak spot in the system and can wear out if excessive engine torque loads are applied through it.
