    A particle moves along the x-axis so that at time t its position is given by s(t)=(t+3)(t-1)^3,t>0. For what values of t is the velocity of the particle decreasing? a) 00 d) The velocity is never decreasing. Thanks in advance.

    The velocity of a particle constrained to move along the x-axis as a function of time t is given by: v(t)=-(13/t_0) sin(t/t_0). a)If the particle is at x=4 m when t = 0, what is its position at t = 5t_0. You will not need the value of t_0 to solve any part

    The acceleration of a particle which moves along the x axis is given by a=4x+5x^(3/2) The particle has speed of 2m/s when x=1m x is in meters a is in m/s^2 evaluate the velocity when x = 8m I know that I need to use kinematic eqn 3 adr = vdv then take the
