To solve this problem we will find the net speed, through the two components given. The vertical component will be found through the energy conservation theorem. Finally with speed we will find the momentum as a function of mass and speed. Given the weight we will divide it by the acceleration to find that mass.
The x component is given as
For conservation of energy the vertical component of velocity would be
Here,
m = Mass
g = Gravitational acceleration
h = Height
Replacing we have that the vertical velocity is
The magnitude of this velocity would be
Finally the momentum of the bale would be
Therefore the momentum of the bale the moment it strikes the ground is
<u>Answer:</u> The molar mass of metal (M) is 47.86 g/mol
<u>Explanation:</u>
Let the atomic mass of metal (M) be x
Atomic mass of
To calculate the mass of metal, we use the equation:
Mass percent of metal = 59.93 %
Mass of metal = x g/mol
Mass of metal oxide = (x + 32) g/mol
Putting values in above equation, we get:
Hence, the molar mass of metal (M) is 47.86 g/mol
A greater weight so the object has greater weight
Answer:
Force = 485000 Newton.
Explanation:
Given the following data;
Mass = 485000 kg
Initial velocity = 20m/s
Final velocity = 25m/s
Time, t = 5 seconds
To find the force;
First of all, we would calculate the acceleration of the train i.e the rate of change of the velocity of the train with respect to time.
Mathematically, acceleration is given by the equation;
Where;
a is acceleration measured in
v and u is final and initial velocity respectively, measured in
t is time measured in seconds.
Substituting into the equation, we have;
Acceleration = (25 - 20)/5
Acceleration = 5/5
Acceleration = 1m/s²
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Force = mass * acceleration
Force = 485000 * 1
Force = 485000 Newton.
