Instantaneous speed.

A body moves from rest with a constant acceleration of 5 m/s2. Its instantaneous speed (in m/s) at the end of 10 sec is

Expert Solution

The instantaneous speed formula is given by

Speed(i) = ds/dt

Where,

ds is the distancedt is the time intervalSpeed(i) is the instantaneous speed

Given that

Acceleration a=5m/s2

Time t=10m/s

We have to determine the instantaneous speed

Acceleration(a)= dv/dt

Instantaneous speed = a×Δt

=5×10

=50m/s

The Instantaneous speed = 50m/s

If the instantaneous value of a voltage in an AC circuit of the communication system (at any time t seconds) is given by V= 142sin(8πt-0.125π) volts, determine: 1). Given that the voltage waveform can also be represented as V=Rsin(ωt+θ), use compound angle identities to resolve the resultant voltage waveform into its two component waveforms: asinωt and bcosωt. 2). In another circuit the voltage, V is made up of two components v1 = (A/3)Sin(t) and v2 = (A/2)Cos(t). Sketch the two...
