A car speeds up on how its built
Answer:
100 foot
Explanation:
Using the formula for calculating range to calculate the speed first as shown;
<h3>Range R = U²sin 2theta/g</h3>
U is the speed
theta is the observe angle
g is the acceleration due to gravity.
200 = U²sin 2(45)/9.8
Usin90 = 200 * 9.8
U² = 1960
U = √1960
U = 44.27 m/s
Get the required altitude
Altitude H = u²/2g
H = 44.27²/2(9.8)
H = 1,959.8329/19.6
<em>H = 99.99 feet</em>
<em>Hence the altitude of the rocket to the nearest foot is 100 foot</em>
Answer:
The answer is A because it is a resource that takes many many years to make more of and we cannot make it ourselves
Explanation:
12N by first law of newton is net force after colloision
The cannon is 17.69 m above the ground level
<h3>Data obtained from the question</h3>
The following data were obtained from the question:
- Horizontal speed (u) = 333 m/s
- Horizontal distance (s) = 622 m
- Height (h) =?
<h3>How to determine the time </h3>
We'll begin by calculating the time taken for the ball to land on the ground. This can be obtained as follow:
- Horizontal speed (u) = 333 m/s
- Horizontal distance (s) = 622 m
- Time (t) =?
s = ut
622 = 333 × t
Divide both sides by 333
t = 622 / 333
t = 1.9 s
<h3>How to determine the height</h3>
The height of the cannon above the ground can be obtained as illustrated below:
- Acceleration due to gravity (g) = 9.8 m/s²
- Time (t) = 1.9 s
- Height (h) =?
h = ½gt²
h = ½ × 9.8 × 1.9²
h = 4.9 × 3.62
h = 17.69 m
