Answer:
The maximum height is reached after 3.75 seconds.
Step-by-step explanation:
Assuming the deceleration due to gravity is unaided by air resistance, gravity causes the ball to lose vertical speed at the rate of 32 ft/s every second. The initial vertical speed of 120 ft/s will decline to zero when t satisfies ...
... 120 ft/s - (32 ft/s²)t = 0
... (120 ft/s)/(32 ft/s²) = t = 3.75 s
The ball will not go any higher after its vertical speed is zero.
B because your allow to ship according to the sample
Answer:
The price of candy bar is 75 cents
Step-by-step explanation:
Let c be the price of candy bar and d be the price of drinks
Then according to given statements
Multiplying equation 1 by 2
Subtracting equation 2 from equation 3
Dividing both sides by 130
Putting d=2 in equation 1
Price of candy bar is $0.75 or 75 cents
Hence,
The price of candy bar is 75 cents
