Answer:
The value of basketball player's autograph a year ago is $280
Step-by-step explanation:
Given as :
The present value of autograph = $ 336.00
The rate of increase of autograph = 20%
The time period = 1 year
Let The value one year ago = $ x
So ,
The value of autograph after n year = The present value × 
Or, $ 336.00 = $ x × 
Or, $ 336.00 = $x × 1.2
∴ x =
= $280
Hence The value of basketball player's autograph a year ago is $280 Answer
The work done in lifting the block is 3430 J
<h3>Calculating work </h3>
From the question, we are to determine the work done in lifting the block
Using the formula,
Work done = mgh
Where m is the mass
g is the acceleration due to gravity
and h is the height
From the question,
m = 50.0 kg
g = 9.81 m/s²
h = 7.00 m
Putting the parameters into the formula,
Work done = 50.0 ×9.8 × 7.00
Work done = 3430 J
Hence, the work done in lifting the block is 3430 J
