In a given reference frame xOy, a point-like particle is moving with velocity v(t)= (t-1 s) m/s5 x+ (t-1 s) m/sc. 1) Determine the value of the exponent d and c in order for the expression to make sense. 2) Determine the position r(t=1s) of the particle by knowing that at the time t=0 the particle is at the position r(t=0) = -0.2 m x+ 0 m . 3) Determine the acceleration a(t)
