Atoy projectile is fired from the ground vertically upward with an initial velocity of 26.5 m/s. the project arrives at its maximum altitude in 2.7s. determine the greatest height the projectile reaches. how do you know?

35.8 m

Explanation:

Given:

Initial Velocity u = 26.5 m/s

Time period t = 2.7 s

To find:

Maximum height H = ?

Solution:

The toy is projected vertically upward. So the motion is happening in y axis

When a projectile reaches its maximum height, at that point its velocity vill be zero

Using equations of motion we can find the height

Verification

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
