Answer:
exponential
Explanation:
type of function that describes the amplitude of damped oscillatory motion is exponential because as we know that here function is
y = A ×
× cos(ωt + ∅ ) ..................................... ( 1 )
here function A ×
is amplitude
as per equation ( 1 )it is exponential
so that we can say that amplitude of damped oscillatory motion is exponential
Answer:
2.43J
Explanation:
Given parameters:
Mass of the arrow = 0.155kg
Velocity = 31.4m /s
Unknown:
Kinetic energy when it leaves the bow = ?
Solution:
The kinetic energy of a body is the energy in motion of the body;
it can be derived using the expression below:
K.E =
m v²
m is the mass
v is the velocity
Solve for K.E;
K.E =
x 0.155 x 31.4 = 2.43J
First do 1.6 m (how far he jumps) 9.8 m/s (what gravity is measured at) then times 2
= 31.36
Sq root = 5.6
I'm pretty sure the energy an object acquires when exposed to a force is known was potential energy.
Answer: 10 m/s
Explanation: Velocity/Time
50/5= 10
