Answer:
B) 40 km West
Explanation:
Let position of B is origin so with respect of City B the position of A is given as
south of city B
now Bus starts from City A and travels a distance of 50 km at 37 degree North of East to reach city C
so it is
now the position of C is given with respect to A
in order to find the position of C with respect to B we can say
so in order to reach at city B from city C bus has to travel 40 km towards West
(10 seconds) / (2 cycles) = (10/2) (sec/cycle) = 5 seconds.
That's the pendulum's period.
Frequency = 1 / (period) = 1/5 per second = 0.2 Hz.
Answer:
V(c)' = 0.325 m/s
V(a)' = 2.19375 m/s
V(b)'' = 0.73125

Answer:
1.65 h
121.39 km
Explanation:
Given that
speed of the driver, v = 99.5 km/h
time spent resting, t = 26 min
Average speed of the driver = 73.6 km/h

Answer:
As per law of conservation of momentum
1 × 10 = 50× v
v = 1/5 m/S
Or
20 cm/s
