Answer:
274N 0.41
Explanation:
As he is sliding down in a constant speed then the force that accelerates him (weight) and the force that slows his down (friction) are equal.
then
<em>friction=mass x gravity x sin(21)</em>
Fr=78kg x 9.8m/s2 x sin(21)=274N
<em>friction= coefficient of kinetic friction x normal force of from the slope</em>
Fr= u x 78kg x 9.8m/s2 x cos(21)=274N
Fr= u x 78kg x 9.8m/s2 x cos(21)=274Nu=274/677=0.41
Answer:
The equation of simple harmonic motion is
Explanation:
Given that,
Amplitude = 5 inches
Frequency
As per the question initial displacement is zero at t = 0 for sine curve.
The displacement is zero so the phase difference will be zero.
We know that,
The general equation of simple harmonic motion
Where, A = amplitude
= angular frequency
= phase shift
We need to calculate the time period
Using formula of frequency
Put the value into the formula
We need to calculate the angular frequency
Using formula of angular frequency
Put the value into the general equation
Hence, The equation of simple harmonic motion is
