The answer would be 187.95 kg.m/s.
To get the momentum, all you have to do is multiply the mass of the moving object by the velocity.
p = mv
Where:
P = momentum
m = mass
v = velocity
Not the question is asking what is the total momentum of the football player and uniform. So we need to first get the combined mass of the football player and the uniform.
Mass of football player = 85.0 kg
Mass of the uniform = <u> 4.5 kg</u>
TOTAL MASS 89.5 kg
So now we have the mass. So let us get the momentum of the combined masses.
p = mv
= (89.5kg)(2.1m/s)
= 187.95 kg.m/s
<span>electrons change momentum, some of them slough off photons. And some of those photons have energy in the visible light range of the electro-magnetic spectrum. </span>
The answer is that it is 1.5 amps
Answer:
The moment of inertia of the bar is 
Explanation:
Given that,
mass of bar = 150 g
Length l = 36 cm
We need to calculate the moment of inertia of the bar
Using formula of moment inertia
Where,
M = mass of the bar
L = length of the bar
Put the value into the formula
Hence, The moment of inertia of the bar is
We have,
- Mass of brook = 87 kg
- Pressure applied by it on the ground = 9800 N/m²
Now, we know that,
We are provided with pressure applied butbwe need to calculate force;
- F = ma
- F = 87 × 9.8 { Accleration due to gravity }
Finally, just put all these values in pressure's formula:
- P = F/A
- 9800 = 87 × 9.8 / A
- 98000/87 × 98 = A
- 1000/87 = A
- 11.49 = A
- 11.5 m²(Approx) = A
