Part a)
Equation of position with time is given as
since this equation is a quadratic equation
so it will be a parabolic graph between t = 0 to t = 1
part b)
at t = 0.45 s
at t = 0.55 s
now the displacement is given as
so the average velocity is given by
part c)
at t = 0.49 s
at t = 0.51 s
now the displacement is given as
so the average velocity is given by
Yes because it’s higher mass the higher it is, the more thermal energy gets absorbed
Answer:
The question is incomplete, the complete question is "A car drives on a circular road of radius R. The distance driven by the car is given by d(t)= at^3+bt [where a and b are constants, and t in seconds will give d in meters]. In terms of a, b, and R, and when t = 3 seconds, find an expression for the magnitudes of (i) the tangential acceleration aTAN, and (ii) the radial acceleration aRAD3"
answers:
a.
b.
Explanation:
First let state the mathematical expression for the tangential acceleration and the radial acceleration.
a. tangential acceleration is express as
since the distance is expressed as
the derivative is the velocity, hence
hence when we take the drivative of the velocity we arrive at
b. the expression for the radial acceleration is expressed as
