At time t = 0 a particle starts moving along a line with equation of motion s(t) = t^3−4t^2+ 6, whereS is meters and t is in seconds.a) Give the velocity and acceleration functions.b) What is the velocity at time t = 2?c) When is the acceleration 2 m/s^2?
Acceleration function of a particle along the x axis is given by a(t)= 2t-3.a) If the velocity at 2 sec is 4 m/s, find the velocity of that object at 5 second. b) Consider the displacement of that object at 2 second is 6 m. Calculate the displacement at 10 ?ec. c) Draw velocity vs time graph for 0 ≤ t ≤ 6 second.
A student begins at rest and then walks north at a speed of v1=0.65m/s. The student then turns south and walks at a speed of v2=0.28m/s. Take north to be the positive direction.
a)What is the student's overall average velocity vavg, in meters per second, for the full trip assuming the student spent equal times at speeds v1 and v2?
b) If the student travels in the stated directions for 30.0s30.0s at speed v1 and 20.0s at speed v2, what is the net displacement, in meters, during the trip?
