Answer:
D. D
Step-by-step explanation:
Where -1.9 is!!
The question states the : opposite of the opposite.
So- we find the opposite of (-1.9) =1.9 and the opposite of that is = -1.9.
So- it is situated at -1.9
Hope this helps!! =)
Answer:
50.75
Step-by-step explanation:
You Just have to multiply length - width - and height - and you're good to go!
Answer:
1.375 seconds
Step-by-step explanation:
One mile is equivalent to 5280 feet. Throwing at 30 miles an hour is 0.5 miles each minute, or one mile every 120 seconds(Unfortunately for the pitcher, I don't think the ball would make it to home plate). That means it travels 1/120 miles each second, or 44 feet(5280/120). The ball will reach home plate in 1.375 seconds(60.5/44).
Answer:
If thrown up with the same speed, the ball will go highest in Mars, and also it would take the ball longest to reach the maximum and as well to return to the ground.
Step-by-step explanation:
Keep in mind that the gravity on Mars; surface is less (about just 38%) of the acceleration of gravity on Earth's surface. Then when we use the kinematic formulas:

the acceleration (which by the way is a negative number since acts opposite the initial velocity and displacement when we throw an object up on either planet.
Therefore, throwing the ball straight up makes the time for when the object stops going up and starts coming down (at the maximum height the object gets) the following:

When we use this to replace the 't" in the displacement formula, we et:

This tells us that the smaller the value of "g", the highest the ball will go (g is in the denominator so a small value makes the quotient larger)
And we can also answer the question about time, since given the same initial velocity
, the smaller the value of "g", the larger the value for the time to reach the maximum, and similarly to reach the ground when coming back down, since the acceleration is smaller (will take longer in Mars to cover the same distance)
