D = distance between th two trains at the start of the motion = 100 miles
V = speed of the faster train towards slower train = 60 mph 
v = speed of the slower train towards faster train = 40 mph 
t = time taken by the two trains to collide = ?
 time taken by the two trains to collide is given as 
t = D/(V + v)
t = 100/(60 + 40) = 1 h 
v' = speed of the bird = 90 mph 
d = distance traveled by the bird
distance traveled by the bird is given as 
d = v' t 
d = 90 x 1 
d = 90 miles

Answer:
The time is 1.8s
Explanation:
The ball droped, will freely fall under gravity.
Hence we use free fall formula to calculate the time by the ball to hit the ground

Where h is the height from which the ball is droped, g is the acceleration due to gravity that acted on the ball, and t is the time taken by the ball to hit the ground.
From the question,
h=16m
Also, let take 

By substitution we obtain,


Diving through by 9.8


square root both sides, we obtain
