Question: Figure shows a 5.00 kg block being pulled along a frictionless floor by a cord that applies a force of constant magnitude 20.0 N but

Figure shows a 5.00 kg block being pulled along a frictionless floor by a cord that applies a force of constant magnitude 20.0 N but with an angle θ (t) that varies with time. When angle θ = 25.0o, at what rate is the block's acceleration changing if

(a) θ(t) = (2.00 x 10–2 deg/s)t and

(b) θ(t) = – (2.00 x 10-2 deg/s)t?
