Answer:
30.63 m
Explanation:
From the question given above, the following data were obtained:
Total time (T) spent by the ball in air = 5 s
Maximum height (h) =.?
Next, we shall determine the time taken to reach the maximum height. This can be obtained as follow:
Total time (T) spent by the ball in air = 5 s
Time (t) taken to reach the maximum height =.?
T = 2t
5 = 2t
Divide both side by 2
t = 5/2
t = 2.5 s
Thus, the time (t) taken to reach the maximum height is 2.5 s
Finally, we shall determine the maximum height reached by the ball as follow:
Time (t) taken to reach the maximum height = 2.5 s
Acceleration due to gravity (g) = 9.8 m/s²
Maximum height (h) =.?
h = ½gt²
h = ½ × 9.8 × 2.5²
h = 4.9 × 6.25
h = 30.625 ≈ 30.63 m
Therefore, the maximum height reached by the cannon ball is 30.63 m
Where the m1 and m2 is the mass of two object. U1 and U2 are the initial velocity of hockey pucks. V1 and V2 are the final velocity of Hockey Pucks.
m2=2kg The initial velocity of both pucks are 0. The v1=8m/s. All you have to do now is find v2
0=4-2v
-4=-2v
v=+2m/s
Answer: +2
The principle of moment can be verified when two known masses are suspended on a uniform meter rule.
<h3>What is principle of moment?</h3>
The principle of moment states that, the sum of clockwise moment is equal to the sum of the anticlockwise moment.
The principle of moment is verified when two known mass (m1 and m2) are suspended on a uniform meter rule.
The clockwise moment will be equal anticlockwise moment of the two masses.
Thus, the principle of moment can be verified when two known masses are suspended on a uniform meter rule.
