malcom is doing a wheely on his motorcycle and moving at 20 m/s with a momentum of 6000 kg m/s when he lays her down. The mass o
1 answer:
Answer:
110 kg
Explanation:
The momentum of the Malcom+motorcycle system is given by:
where
(m+M) is the total mass of the system, with
m = mass of Malcom
M = 190 kg (mass of the motorcycle)
v = 20 m/s velocity
Since we know the momentum:
p = 6000 kg m/s
We can re-arrange the equation to find the mass of Malcom:

Answer:
The maximum velocity is 1.58 m/s.
Explanation:
A spring pendulum with stiffness k = 100N/m is attached to an object of mass m = 0.1kg, pulls the object out of the equilibrium position by a distance of 5cm, and then lets go of the hand for the oscillating object. Calculate the achievable vmax.
Spring constant, K = 100 N/m
mass, m = 0.1 kg
Amplitude, A = 5 cm = 0.05 m
Let the angular frequency is w.
The maximum velocity is
Answer:
He requires 1 gram of mass.
Explanation:
The density is defined as:
(1)
Where m is the mass and V is the volume.
Then, m can be isolated from equation 1 in order to determine the mass.
(2)
Hence, he requires 1 gram of mass.
