A particle’s trajectory is described by x =(12t3−2t2)m and y =(12t2−2t)m, where t is in s.
a. What is the particle’s speed at t=0s ? v = m/s
b. What is the particle’s speed at t=5.0s ? Express your answer using two significant figures. v = m/s
c. What is the particle’s direction of motion, measured as an angle from the x-axis, at t=0 s ? Express your answer using two significant figures. θ =
d. What is the particle’s direction of motion, measured as an angle from the x-axis, at t=5.0s ? Express your answer using two significant figures. θ =
