Answer:
<em>The range is 15.15 m and the time in the air is 1.01 s</em>
Explanation:
<u>Horizontal Motion</u>
When an object is thrown horizontally (with angle 0°) with a speed v from a height h, it follows a curved path ruled exclusively by gravity until it eventually hits the ground.
The range or maximum horizontal distance traveled by the object can be calculated as follows:

To calculate the time the object takes to hit the ground, we use the equation below:

The cannon is shot from a height of h=5 m with an initial speed of v=15 m/s. The range is calculated below:

d = 15.15 m
The time in the air is:

t = 1.01 s
The range is 15.15 m and the time in the air is 1.01 s
Answer:
10kg
Explanation:
Let PE=potential energy
PE=196J
g(gravitational force)=9.8m/s^2
h(change in height)=2m
m=?
PE=m*g*(change in h)
196=m*9.8*2
m=10kg
