Answer:

Object is thrown with a velocity of 56.74 m/sec

Step-by-step explanation:

We have given height h = 50 feet

When the object reach at its maximum height its final velocity will be o

So final velocity v = 0 m/sec

Acceleration due to gravity g=-32.2feet/sec^2 ( Negative sign is due to upward direction )

From third equation of motion

v^2=u^2+2gh

0^2=u^2-2\times 32.2\times 50

u^2=3220

u=56.74m/sec

So object is thrown with a velocity of 56.74 m/sec

Answer:

40 ft/sec

Step-by-step explanation:

height h = 50 ft

final velocity v would be zero.

acceleration a = -32 ft/sec^2

we kn that

u^2=v^2+2ah

u^2= 0^2- 32×50

u= √(32×50)

u= 40 ft/sec

the object must be thrown with the velocity of 40 ft/sec

Dawn has 5\6 yard of lace. She uses 4\5 of it on a dress and the rest on a jewel box. How much does she use on the jewel box
mr_godi [17]

Answer:

Jewelry box:  1/6 yard

Step-by-step explanation:

4/5 (not 4\5) of her 5/6 yard goes into a dress:   (4/5)(5/6 yd) = 2/3 yard.

This is the same as 4/6 yard.  The amount of lace remaining, to be used on a jewelry box, is 5/6 - 4/6, or 1/6 yard.
