A student buys a plastic dart gun and tries to find the maximum horizontal range. The student shoots the gun straight up and it takes 3.7 seconds for the dart to return back to the height of the barrel. What is the maximum horizontal range of the gun?

The value is

Explanation:

From the question we are told that

    The total time of flight is  

Generally from kinematic equation

So v is the velocity at maximum height and the value is  v = 0 m/s

So

=>  

Here u  is the initial velocity of the dart as it leaves that gun  

Gnerally the horizontal range of the dart is mathematically represented as

For maximum horizontal range the value of          

So

=>    

car a and b are moving in opposite directions

plz mark.me the brainliest i rlly need this kind of yours in exchange

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them
