Answer:
angular frequency is 209439.51 rad/sec
maximum displacement is 0.010504 m
Explanation:
Given data
mass = 2.3 × 10^-20 kg
period = 3.0 × 10^-5 s
maximum speed = 2.2 × 10^3 m/s
to find out
the angular frequency and maximum displacement
solution
we know angular frequency formula that is
angular frequency = 2 π / period
put here period value we get angular frequency
angular frequency = 2 π / 3.0 × 10^-5
angular frequency is 209439.51 rad/sec
maximum displacement formula is
speed = angular frequency × maximum displacement
put all value and we get maximum displacement
maximum displacement = 2.2 × 10^3 / 209439.51
maximum displacement is 0.010504 m
Part A:
Acceleration can be calculated by dividing the difference of the initial and final velocities by the given time. That is,
a = (Vf - Vi) / t
where a is acceleration,
Vf is final velocity,
Vi is initial velocity, and
t is time
Substituting,
a = (9 m/s - 0 m/s) / 3 s = 3 m/s²
<em>ANSWER: 3 m/s²</em>
Part B:
From Newton's second law of motion, the net force is equal to the product of the mass and acceleration,
F = m x a
where F is force,
m is mass, and
a is acceleration
Substituting,
F = (80 kg) x (3 m/s²) = 240 kg m/s² = 240 N
<em>ANSWER: 240 N </em>
Part C:
The distance that the sprinter travel is calculated through the equation,
d = V₀t + 0.5at²
Substituting,
d = (0 m/s)(3 s) + 0.5(3 m/s²)(3 s)²
d = 13.5 m
<em>ANSWER: d = 13.5 m</em>
