Rubric: a: 1 point for velocity of B with respect to origin, 1 point for velocity of A with respect to origin, 1 point for velocity of B with respect

to A at t=10s with units, b: 1 point for acceleration of A with respect to origin, 1 point for acceleration of B with respect to origin, 1 point for acceleration of A with respect to B at t=5s with units Two objects are moving in 2 dimensions, object A has coordinates x =4t+0.2t3,y = 0 and object B has coordinates x = 0,y = 2t2 +t, where t is measured in s and x and y in m. a. Calculate the velocity of object B relative to object A at t = 10 s. b. Calculate the acceleration of object A relative to object B at t = 5 s.
