Answer:
the horizontal distance covered by the cannonball before it hits the ground is 327.5 m
Explanation:
Given;
height of the cliff, h = 210 m
initial horizontal velocity of the cannonball, Ux = 50 m/s
initial vertical velocity of the cannonball, Uy = 0
The time for the cannonball to reach the ground is calculated as;
The horizontal distance covered by the cannonball before it hits the ground is calculated as;
Therefore, the horizontal distance covered by the cannonball before it hits the ground is 327.5 m
Let's see
Momentum be P
On comaparing
- c=1
So
- b-3c=1
- b-3=1
- b=1+3
- b=4
and
- -a-b=-1
- -a-4=-1
- -a=-1+4=3
- a=-3
So the unit is
- DV⁴/F³
