Answer:
The time taken for the paint ball to hit the ground is
The distance of the landing point from the tower is
Explanation:
From the question we are told that
The height of the tower is
The speed of the paintball in the horizontal direction is
Generally from kinematic equation we have that
Here u is the initial velocity of the paintball in the vertical direction and the value is 0 m/s , this because the ball was fired horizontally
a is equivalent to
t is the time taken for the paintball to hit the ground
So
=>
Generally the distance of its landing position from the tower is
=>
=>
Given :
You drive 200 miles in 3 hours before stopping for lunch and gas. After lunch you travel 250 miles in an hour and a half.
To Find :
Average speed.
Solution :
We know, average speed is given by :
Therefore, average speed of the journey is 100 miles/hr.
Hence, this is the required solution.
