Answer:
After 4s
Step-by-step explanation:
Given the ball is initially projected upwards with a velocity of 64ft per sec and we are required to find the time at which it reaches the ground .There are many approaches to solve this problem we will follow this one:
It is also known as the time of flight for the ball which can be found by doubling the time taken for the ball to reach to its maximum height or the point where velocity is zero.
Now 
For the time taken to reach the max height 
.
Which implies that -32t+v=0.
∴Time taken to travel halfway through the path =2sec.
∴total time =
Answer: 416 boxes
Step-by-step explanation:
Hi, to answer this question we have to calculate the volume of each box and the volume of the storage space.
Since both are rectangular prisms:
Volume = length x width x height
Box of t -shirts = 20 x 16 x 12 = 3,840 cubic feet
Storage = 200 x 200 x 40 = 1,600,000 cubic feet
Next, we have to divide the storage's volume by the volume of each box:
1,600,000 / 3,840 = 416.6 =416 boxes
