A car is travelling at a velocity of 10 kmh -1 on a straight road. The driver of car throws a parcel with a velocity of 10 √ √ 2 kmh -1 when car is passing by a man standing on the side of a road. If parcel just reaches the man, the direction of throw makes following angle with the direction of car
Text Solution
Verified by ExpertsThe correct answer is:
A
When the car is exactly opposite, the man at least distance, the bag will reach him when thrown with velocity v 0 .
sin θ θ = 
or θ θ = 45 0
∴ ∴ total angle between v c and v b is 90 + 45
= 135 0
