Explanation:

We are not asked what to look for, bot we can as well get the time taken by the bird to cover the distance at that speed.

Given

average speed = 2.4m/s

Distance = 1.3m

From the formula

Speed = Distance/Time

Time = Distance/Speed

Time = 1.3/2.4

Time = 0.542secs

Hence the total time covered by the bird is 0.542secs

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

the components of a vector are the parts of the vectors that are to each other.
