Figure Q3 A car A is travelling along a straight path, while a lorry B is travelling along a circular path having a radius of curvature of 200 m as shown in Figure Q3. At the instant shown, car A travel at the velocity of (150+X) km/h while lorry B travel at the velocity of 80 km/h. Also at this instant, car A has an increase velocity of 7000 km/h? and lorry B has a decrease velocity of 4500 km/h². The angle between straight path of car A and the horizontal line is 0=65°. (a) Calculate the magnitude and direction of velocity of lorry B with respect to car A. ([C3],

Question

Use your matrix number by adding the last three digits to get the value of X on the velocity
of plane A. The value of X will then need to be added with the digit of 150 as follows;
Example; If your matrix number is AD190251,
Velocity of plane A, VA = 150 + X km/h
X = (2 + 5 + 1) = 8
Therefore, the velocity of plane A, VA = 150 + X, = 150 + 8 = 158 km/h.

SO MY LAST THREE DIGITS ARE: 008

A
v(150+ X)kmh
Vg- 80 km/h
65
a4 = 7000 km/ h?
B
ав — 4500 kmт/h?

Figure Q3
A car A is travelling along a straight path, while a lorry B is travelling along a circular path
having a radius of curvature of 200 m as shown in Figure Q3. At the instant shown, car A
travel at the velocity of (150+X) km/h while lorry B travel at the velocity of 80 km/h. Also
at this instant, car A has an increase velocity of 7000 km/h² and lorry B has a decrease
velocity of 4500 km/h². The angle between straight path of car A and the horizontal line is
0=65°.
