(2nd variant, 7kg is 3 times faster than 21kg)
Answer:
d = 18 m
Explanation:
Given that,
The speed of a baseball, v = 36 m/s
We need to find the distance from the mound to home plate if the ball takes 0.5 seconds to leave the pitcher's hand and cross the plate.
Let the distance be d. We can find it using the formula,
Speed = distance/time
or
So, the required distance is equal to 18 m.
A a wire, a wire is connected between the positive and negative ends of the eletrical energy source and connects all the components in between.
This answer would be false no they can not do that.
Answer:
A d-t graph's slope is equivalent to the speed and direction while a v-t graph's slope is equal to its acceleration. A constant slope for a d-t graph means that the speed is constant. The area underneath a v-t graph would be its distance.
