Question

Cars A and B are traveling on circular portions of a road. At the instant shown, the speed of A is
decreasing at the rate of 7 m/s2, and the speed of B is increasing at the rate of 2 m/s2. For the
positions shown, determine
a. The velocity of B relative to A;
b. The acceleration of B relative to A.​

Answer 1

Answer:

Racing cars A and B are traveling on circular portions of a race track. At the instant shown, the speed of A is decreasing at the rate of 8 m/s2, and the speed of B is increasing at the rate of 3 m/s2. For the positions shown, determine (a) the velocity of B relative to A, (b) the acceleration of B relative to A.

Step-by-step solution:

Step 1 of 5

(a) Solution:

Acceleration of Car A = -8m/s2

Acceleration of Car B =

Velocity of Car A =

Velocity of Car B =

Relative velocity of ‘B’ = with respect to Car A
