The answer is C (^‿^✿)
All you have to do is subtract 154.50 by 65.50 and add that answer to 275.25
Answer:
t = 8.2 sec
Step-by-step explanation:
the ball will move with uniform deceleration due to gravity until it reaches the highest point at which v = 0 then will change its direction and continue with uniform acceleration until it hits the ground.
the time the ball takes to reach the highest point equals the time it takes to return to the ground again.
to calculate the total time, we calculate the first half then multiply it by 2
we use the first equation because we have all the variables except time
v = 0 , u = 40 , a = -9.8
0 = 40 - 9.8t
t = 4.1 sec
total time = 4.1 x 2 = 8.2 sec
Answer: mass and the distance apart are the factors that affect the force of gravity
Step-by-step explanation:
To increase the force of gravity on an object, you must increase the mass of the object and decrease the distance between objects.

Answer:
27,28,29
Step-by-step explanation:
x+x+1+x+2 =84
3x +3 =84
3x=84-3
3x=81
x=81 :3
x=27 (the first number
27 +1=28 (the second number
27 +2 =29 (the third number
