Answer:
- The speed will be

Explanation:
We can use the following kinematics equation

where
is the final speed,
its the initial speed, a is the acceleration, and d the distance.
The force will be tripled, the force is:

in 1D

Now, for the original problem, we have



For the second problem, we have

starting from the rest, we have the same initial velocity.


As the force is tripled, we have:


But the mass its the same, so


So the acceleration its also tripled.


As the distance traveled by the arrow must also be the same, we have:





And this will be the speed from the arrow leaving the bow.
Answer:
47 m/s
Explanation:
golf club mass, mc = 180 g
golf ball mass, mb = 46 g
initial golf club speed, vc1 = 47 m/s
final golf club speed, vc2 = 35 m/s
initial golf ball speed, vb1 = 0 m/s
final golf ball speed, vb2 = ? m/s
The total momentum is conserved, then:
mc*vc1 + mb*vb1 = mc*vc2 + mb*vb2
Replacing with data and solving (dimension are omitted):
180*47 + 46*0 = 180*35 + 46*vb2
vb2 = (180*47 - 180*35)/46
vb2 = 47 m/s
Answer:
DNA identical to the DNA of the parent
Explanation:
Answer:
The acceleration would double
Explanation:
Assuming the same box and spring, the maximum acceleration is proportional to amplitude. When the amplitude doubles, the acceleration would double.
__
A spring is generally considered to have a linear force vs. distance characteristic. Hence, doubling the distance doubles the force. The acceleration is proportional to the force.
