Answer:
<h2>92.86 kg </h2>
Explanation:
lThe mass of an object given only it's force and acceleration can be found by using the formula
f is the force
a is the acceleration
From the question
f = 195 N
a = 2.1 m/s
We have
We have the final answer as
<h3>92.86 kg</h3>
Hope this helps you
Answer:
1.241 kg
Explanation:
The mass of the man in kg is 195 pound * (1/2.2) kg/pound = 195/2.2 = 88.64 kg
If 1.4% of the mass of a human body is calcium, then the mass of calcium inside the 88.64 kg man is
1.4% * 88.64 = 88.64*1.4/100 = 1.241 kg
So there's 1.241 kg of calcium inside a 195-pound man
Answer:
a = 3 [m/s²]
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
Vf = final velocity = 60 [m/s]
Vo = initial velocity = 20 [m/s]
a = acceleration [m/s²]
t = time = 10 [s]
Now replacing these values we have:
60 = 20 + (a*10)
60 - 20 = 10*a
30 = 10*a
a = 3 [m/s²]
the object's speed and centripetal acceleration in a circle with a constant radius is the exponential curve going up.
acceleration is the rate of change in both speed and direction of velocity over time. When something moves faster or slower in a straight line, it is said to have been accelerated. Because the direction is constantly shifting, motion on a circle accelerates even when the speed is constant. Both effects add to the acceleration for all other types of motion.
It is a vector quantity because acceleration has both a magnitude and a direction. Another vector quantity is velocity. The velocity vector change over a given period of time, divided by that period of time, is the definition of acceleration. The upper limit of the ratio of velocity change provides instantaneous acceleration (at a specific time and place).
