Question
Choose the one alternative that best completes the statement or answers the question. The components of the sum of these vectors are given by Choice 1 Choice 2 Choice 3 Choice 4 Object A has a position as a function of time given by r vector _A(t) = (3.00 m/s)ti + (1.00 m/s^2)t^2j. What is the distance between object A and object B at time t = 5.00 s? 29.8m 34.6m 3.46m 45.0m 50.2m An object has a velocity v vector_0(t) = (3.00 m/s)i + (1.00 m/s)j at time t = 0.00s. The acceleration of the object is a vector(t) = (2.00 m/s^3)ti + (1.00 m/s^4)j. If the object is located at r vector_0(t) = (1.00 m)i + (-1.00 m) at time t = 0.00s., what is the position of the object at time t = 1.00 s? (0.333 m)i + (0.0833 m)j (2.72 m)i + (6.14 m)j (2.00 m)i + (1.00 m)j (4.33 m)I + (0.0833 m)j (5.32 m)i + (1.34 m)jExplanation / Answer
you have asked 2 different question.As per chegg guidelines i can only answer one.Please raise different question for other one
2)
rA(t=5sec)=(3*5i)+(1*5^2)j
=15i+25j
rB(t=5sec)=(4*5i)-(1*5^2j)
=20i-25j
rB(t=5sec)-rA(t=5sec)
=20i-25j-15i-25j
=5i-50j
resulatant R=sqrt(5^2+(-50)^2)
=50.2m---answer
