(a) The pitcher must throw the ball at 27.7 m/s
The momentum of an object is given by:
where
m is the mass of the object
v is the object's velocity
Let's calculate the momentum of the bullet, which has a mass of
m = 2.70 g = 0.0027 kg
and a velocity of
Its momentum is:
The pitcher must throw the baseball with this same momentum. The mass of the ball is
m = 0.146 kg
So the velocity of the ball must be
So, the pitcher must throw the ball at 27.7 m/s.
(b) a. The bullet has greater kinetic energy
The kinetic energy of an object is given by
where m is the mass of the object and v is its speed.
For the bullet, we have:
For the ball:
So, the bullet has greater kinetic energy.
Answer:
To identify the problem
Explanation:
The first step in the problem-solving process is to identify the problem. It is not as simple as it sounds as different people may have different ideas of what the "problem" is. Clearly stating the problem and getting everyone involved to agree is an important first step.
Answer:0.507m
To answer this question, you need to know how to calculate a cube volume. Cube volume is calculated by multiplying the length^3, make its unit become cubic meter.
In this case we know the volume is 130L and asked how long is the length in meter. Then you need to convert the liter into m3. The calculation would be:
V=R^3
130L= R^3
R= 3<span>√(130m3/1000)
R= 5.065797/10 m
R= 0.506579m
Rounded up to 0.507m</span>
Answer:
<h2>1672 kgm/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 60.6 × 27.6
<h3>1672.56 kg.m/s</h3>
Hope this helps you
