Answer:
1010 m
Explanation:
The following data were obtained from the question:
Height (h) of cliff = 500 m
Horizontal velocity (u) = 100 m/s
Horizontal distance (s) =?
Next we shall determine the time taken for the cannon ball to hit the ground. This can be obtained as follow:
Height (h) of cliff = 500 m
Acceleration due to gravity (g) = 9.8 m/s²
Time (t) =?
h = ½gt²
500 = ½ × 9.8 × t²
500 = 4.9 × t²
Divide both side by 4.9
t² = 500/4.9
Take the square root of both side
t = √(500/4.9)
t = 10.1 s
Finally, we shall determine the horizontal distance travelled by the cannon ball.
This can be obtained by using the following formula (s = ut) as illustrated below:
Horizontal velocity (u) = 100 m/s
Time (t) = 10.1 s
Horizontal distance (s) =?
s = ut
s = 100 × 10.1
s = 1010 m
Thus, the cannon ball was launched 1010 m away from the cliff.
#1
mass of Sam = 75 kg
velocity of Sam = 18 m/s
now for momentum we can use
#2
Momentum of football = momentum of bullet
#3
As per Newton's law we know that net force is given as
now we have
also we know that
form above equation we have
#4
As per Newton's law we know that net force is given as
now we have
also we know that
form above equation we have
You didn't say the following answers but it's Joule (J). If this answer doesn't match the offered ones, you can ask me again
What are the following options or choices for this question?
Answer:
<h2>6 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>6 m/s²</h3>
Hope this helps you
