Question

At the instant shown, cars A and B are traveling at the speeds vA = 21km/h and vB = 63km/h

1?If B is accelerating at 1150km/h2 while A maintains a constant speed, determine the velocity of A with respect to B .

2. Determine the acceleration of A with respect to B

At the instant shown, cars A and B are traveling at the speeds vA = 21km/h and vB = 63km/h 1?If B is accelerating at 1150km/h2 while A maintains a constant speed, determine the velocity of A with respect to B . 2. Determine the acceleration of A with respect to B

Explanation / Answer

Va = 5.833 m/s mag
Va = - 4.12 i + 4.12 j
Vb = 17.5 i m/s

aA = 0.24 i + 0.24 j
ab = 0.088 i

2 ) answer = aA- aB = 0.152 i + 0.24 j

1)Va - Vb = - 21.62 i + 4.12 j
