Explanation :
When a ball is tossed from an upper storey window off a building, the height of the object as a function of time is given by :
Here, u = 8 m/s
The ball strikes at an angle of 20 degrees below the horizontal. We need to find the time taken by the ball to reach a point 10 meters below the level of launching such that, h (t) = 10 m and a = g = 9.8
After solving the above equation, t = 0.855 seconds
So, the ball will take 0.855 seconds to reach a point 10 m below the level of launching. Hence, this is the required solution.
Answer:
The value is
Explanation:
From the question we are told that
The horizontal speed is
The horizontal distance is
Generally the time taken by the hot magma in air before landing is mathematically represented as
=>
=>
Generally the initial vertical velocity of the magma when it was lunched is
Then the final velocity of the magma when it hits the ground is mathematically represented s
Here the negative sign mean that the direction of the velocity is towards the negative y -axis
So
=>
