- Find the arc length parameter along the given curve from the point where t= 0 by evaluating the integral s(t) = | |v(7)| dt. Then find the length of the indicated portion of the curve r(t) = 6cos ti+ 6sintj+ 4t k, where 0sts T. The arc length parameter along the curve, starting at t= 0 is s(t) =.You're caught running a red light on Hwy 316. Attempting to impress the skeptical patrol officer with your physics knowledge, you claim that you were traveling so fast that the red light (693 nm) appeared yellow (582 nm) to you. How fast would you have been traveling (in mi/hr) if that had been the case?A particle is moving along a line with position given by s(t)=t3−(9/2(t2 ))+6t−5 measured in meters, with t≥0 measured in minutes, and the positive direction meaning forward. a) Find the equation for the velocity at time t. Give units, and find times the times the particle is moving forward. b) Find the equation for the velocity at time t. Give units, and find times the times the particle is moving backwards. c) Find the total distance travelled by the particle. d) Find the equation of the acceleration at time t. Give the units, and find the times when the velocity of the particle is not changing. e) Find the displacement.

- P-3 Please help me with this problem very clearly with step by step explanation. Note: This problem is not very difficult if you remember to distinguish between the coordinate of the observation point and that of the integration.An experimentalist in a laboratory finds that a particle has a helical path. The position of this particle in the laboratory frme is given by r(t)= R cos(wt)i + R sin(wt)j + vztk R,vz, and w are constants. A moving frame has velocity (Vm)L= vzk relative to the laboratory frame. In vector form: A)What is the path of the partical in the moving frame? B)what is the velocity of the particle as a function of time relative to the moving frame? C)What is the acceleration of the particle in each frame? D)How should the accelerartion in each frame be realted?Does your answer to part c make sense?An airline passenger drops a coin while the plane is moving horizontally at 260 m/s.
