A helicopter rises from rest on the ground vertically upwards with a constant acceleration . A food packet is dropped from the helicopter when it is at a height h. The time taken by the packet to reach the ground is close to [ is the acceleration due to gravity ]:
Given below are two statements:One is labelled as Assertion A and the other is labelled as Reason R
Assertion A: Two identical balls A and B thrown with same velocity at two different angles with horizontal attained the same range R. If A and B reached the maximum height and respectively,then
Reason R: Product of said heights.
Question: Choose the correct answer:
A particle starts from the origin at t=0 with an initial velocity of and moves in the x-y plane with a constant acceleration The x-coordinate of the particle at the instant when its y-coordinate is 32 m is D meters. The value of D is :
