Answer:
<h2>15m/s</h2>Explanation:
The equation for a traveling wave as expressed as y(x, t) = A cos(kx − t) where An is the amplitude f oscillation,
is the angular velocity and x is the horizontal displacement and y is the vertical displacement.
From the formula; where;
Before we can get the transverse speed, we need to get the frequency and the wavelength.
frequency = 1/period
Given period = 2/15 s
Frequency =
frequency = 1 * 15/2
frequency f = 15/2 Hertz
Given wavelength = 2m
Transverse speed
Hence, the transverse speed at that point is 15m/s
Answer:
Explanation:
Given:
- mass of car,
- distance of skidding after the application of brakes,
- coefficient of kinetic friction,
<u>So, the energy dissipated during the skidding of car:</u>
<em>Frictional force:</em>
where N = normal reaction by ground on the car
<em>Now from the work-energy equivalence:</em>
is the dissipated energy.
