Multiple ChoiceThe velocity of a plane as a function of time is given by v=0.5tı^−2cos(t)ȷ^v=0.5t\(\operatorname{î}\)-2\(\cos\]\left\)(t\(\right\))ĵ. If the plane started from a point r=5.0ı^r=5.0\(\operatorname{î}\) at t=0t=0, what is it's position at t=12st=12s?1views
Multiple ChoiceA dog running around a park has a velocity described by v=(0.03t2−2.5)ı^+(−0.1t+2)ȷ^v=\(\left\)(0.03t^2-2.5\(\right\))î+\(\left\)(-0.1t+2\(\right\))ĵ. What is the dog's displacement vector in unit-vector notation from t=15st=15s to t=30st=30s?1views
