Atoy rocket is shot straight up into the air with an initial speed of 45.0 m/s how long does it takes for the rocket to reach it's highest point ?

Explanation:

Given that,

Initial speed of the toy rocket, u = 45 m/s

Let t is the time taken by the rocket  to reach it's highest point. At the highest point the final speed of the rocket is 0. Using equation of kinematics to find the value of t as :

Here, a = -g

t = 4.59 seconds

So, the rocket will take 4.59 seconds to reach its highest point. Hence, this is the required solution.

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.
