Answer:
-81.2361 m/s
Explanation:
15 m/s 15 m/s
- 9.81 m/s^2= 96.2361 - 96.2361
It will take for the ball to reach its peak 81.2361 m/s if a ball is thrown straight up into the air with a velocity of 15 m/s.
15 m/s
- 9.81 m/s^2= 96.2361
Which formula has been used for change in velocity?Use the formula for change in velocity equal the acceleration times the time, considering that the only acceleration acting is that of "g" (g = 9.8 m/s^2). Consider also that at the top of the trajectory is when the velocity becomes zero and the motion changes from upwards to downwards.It takes the tennis ball approximately 0.78 seconds to reach the maximum height.
Calculate the ball's greatest height using the vertically modelling method, h = -16t2 + vt + s, where v is just the initial velocity at feet/second and s is indeed the height in feet.
Zero The ball travels upward when you throw it, but because gravity is pulling on it, its speed diminishes as it ascends.The ball begins to slow down, and during the peak of its journey, it has zero velocity.
Therefore, It will take for the ball to reach its peak 81.2361 m/s if a ball is thrown straight up into the air with a velocity of 15 m/s.

Explanation:
Lauren's SUV was detected exceeding the posted speed limit of 60 kilometers per hour, how many kilometers per hour over the limit would she have been traveling if she had covered a distance of 10 kilometers in 6 minutes? (6 minutes = 0.1 hr)
40 mph
this is because if we multiply both by 6, we get 60 and 36 minutes but we cant have 36 minutes since it has to be 60 so we can get mph so we would have to multiply both by 10 makeing the time 60 and the kilometers 100 and 60 minus 100 is 40
Write a report on waves. Some questions you might consider are: What makes a wave? Why are some waves small and some large? How are waves classified? Are there different kinds of waves? What happens when a wave meets the shore? Where in the world do you find the best waves for surfing?
Answer:
The waves have energy that wave back and forth because the waves are never still, they are always moving. There are different types of waves because sometimes (like a tsunami) the waves are affected by other things like the earth plates. Portugal is one of the best places to surf because they have waves that can reach up to 6 to 15 feet high!
