A 1 kg ball is thrown straight up into the air and its height is recorded every second until it reaches the ground a little more than 3 seconds later. The height of the ball above the ground is shown in the table. What is the potential energy of the ball at each time? Gravitational potential energy can be calculated by multiplying the mass, the height, and the acceleration due to gravity (9.8 m/s2). Acceleration due to gravity can be rounded to 10 m/s2.

step-by-step explanation:

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

answer: x=60

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
