Answer:
The value is
Explanation:
From the question we are told that
The diameter of each wheel is
The mass of the motorcycle is
The rotational kinetic inertia is
The mass of the rider is
The velocity is
Generally the radius of the wheel is mathematically represented as
=>
=>
Generally from the law of energy conservation
Potential energy attained by system(motorcycle and rider ) = Kinetic energy of the system + rotational kinetic energy of both wheels of the motorcycle
=>
=>
Here is the angular velocity which is mathematically represented as
So
Here
=>
Work done by force is given by formula
now here work done against friction is given so force of friction here is
It moved by three corridors with each measures
so total distance will be
now from above formula of work done we will say
so above is the work done to move three corridors
Answer:
x = ½ aw t²
x = d − ½ az t²
Explanation:
The position of each car at time t is:
x = x₀ + v₀ t + ½ at²
For car W:
x = 0 + (0) t + ½ aw t²
x = ½ aw t²
For car Z:
x = d + (0) t + ½ (-az) t²
x = d − ½ az t²
Solving the system of equations for x will give us the location the cars meet (relative to car W's starting point).
Answer:
The objects morion will remain the same
Explanation:
Answer:
Assuming no air friction,
the time it takes to fall 10 m = t = √2h/g = √(20/9.8) = 1.43 s
horizontal distance = 5 m
horizontal speed = distance/time = 5/1.43 = 3.5 m/s ANS
Explanation:
i hope this helps!
