Explanation:
The range <em>R</em> of a projectile is given the equation
The maximum range is achieved when so our equation reduces to
We can solve for the initial velocity as follows:
or
To find the maximum altitude H reached by the missile, we can use the equation
At its maximum height H, so we can write
or
Answer:
0.85 m/s²
Explanation:
Acceleration is change in velocity over change in time. In mathematically, it can be expressed as:
Our final velocity is given to be 17 m/s in 20 seconds. Initial velocity is at starting point which is 0 m/s in 0 second. Therefore:
Therefore, the acceleration of a horse from starting point to 17 m/s in 20 seconds is 0.85 m/s²
