Question

An arrow is launched straight up from the ground with an initial velocity of 23.4m/s how long until it reaches its highest point

Answer 1

t = 2.388 seconds

Step-by-step explanation:

Initial velocity is 23.4 m/s

At the highest point, the velocity will be 0 m/s

We can use the equation

`v = u+at`

V is the final velocity at the highest point

U is the initial velocity

A is the gravity pulling down on the ball

T is the time in seconds

We plug in the numbers

`0 = 23.4 - 9.8t`

`t = 2.387755102`
