Answer:
The x-component of the velocity is 16.07 m/s
The y-component of the velocity is 19.15 m/s
Explanation:
Given;
initial velocity of the football, u = 25 m/s
angle of projection, θ = 50⁰
The x-component of the velocity (horizontal component) is given as;
![V_x = Vcos(50^0)\\\\V_x = 25 \ m/s \ \ \times \ \ 0.6428\\\\V_x = 16.07 \ m/s](https://tex.z-dn.net/?f=V_x%20%3D%20Vcos%2850%5E0%29%5C%5C%5C%5CV_x%20%3D%2025%20%5C%20m%2Fs%20%5C%20%5C%20%5Ctimes%20%5C%20%5C%200.6428%5C%5C%5C%5CV_x%20%3D%2016.07%20%5C%20m%2Fs)
The y-component of the velocity (vertical component) is given as;
![V_y = Vsin(50^0)\\\\V_y = 25 \ m/s \ \ \times \ \ 0.766\\\\V_y = 19.15 \ m/s](https://tex.z-dn.net/?f=V_y%20%3D%20Vsin%2850%5E0%29%5C%5C%5C%5CV_y%20%3D%2025%20%5C%20m%2Fs%20%5C%20%5C%20%5Ctimes%20%5C%20%5C%200.766%5C%5C%5C%5CV_y%20%3D%2019.15%20%5C%20m%2Fs)
Answer:
2.55 m
Explanation:
Elastic energy = gravitational energy
½ kx² = mgh
h = kx² / (2mg)
h = (200 N/m) (0.05 m)² / (2 × 0.010 kg × 9.8 m/s²)
h = 2.55 m
Answer:
<h2>
38,769.23 miles</h2>
Explanation:
given:
A car is traveling at an average speed of 70 m/s.
find:
How many km would the car travel in 6.5 hrs. ?
solution:
distance = velocity over time
let velocity = 70 m/s
time = 6.5 hrs.
convert velocity 70 m/s into m/h for consistency of units.
<u>70 mi. </u> x <u>3600 sec.</u> = 252,000 mi/hour
sec. 1 hr.
now plugin values into the formula d = v/t
d = <u>252,000 miles/hour </u>
6.5 hours
d = 38,769.23 miles
therefore, the distance travelled in 6.5 hours with a speed of 70 m/s is 38,769.23 miles
I think you forgot to give the options along with the question. I am answering the question based on my knowledge and research. The criteria responsible for deciding whether a heterogeneous mixture is a colloid or a suspension is whether the <span>particles remain suspended for an extended period of time. I hope it helps you.</span>
