A car is travelling at a velocity 10 km h -1 on a straight road. The driver of the car throws a parcel with a velocity 10 
km h -1 with respect to the car, when the car is passing by a man standing on the side of the road. If the parcel is to reach the man, the direction of throw makes the following angle with the direction of motion of the car
A
135°
B
45°
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
In the vector diagram, 
and 
represent the velocity vectors for the car and the parcel, respectively. 
is the resultant velocity vector. Let 
be the angle between 
and 
. Then,
