To find the kinetic energy . You have to use this equation : 1/2m(v^2) .
Velocity units =m/s
Acceleration is the rate of change of velocity
a =timechange in velocity
Therefore SI units of acceleration is ms−1/s=s2m
From the calculations, the acceleration of the elevator is obtained as 1.5m/s^2
<h3>What is acceleration?</h3>
The term acceleration has to do with the rate of change of velocity with time.
Given that;
u = 9.2 m/s
v = 15.8 m/s
t = 3.8
a = ?
The v = u + at
a = v - u/t
a = 15 - 9.2/3.8
a = 1.5m/s^2

Answer:
Option B is the correct answer.
Explanation:
Period of a spring is given by the expression
Here, spring constant, k = 110 N/m
Mass = 0.41 kg
Substituting,
Option B is the correct answer.
The specific heat capacity of different substances vary for the same reason that different substances have different melting and boiling points to one another. If the bonds between atoms are stronger, it will require more energy to heat up the substance.Sep 8, 2018
