How long will it take a rocket traveling at 8 km/s to reach 20 km? (please include the equation)

Answers

Answer 1

Answer:

Step-by-step explanation:

Use the second kinematic formula

[tex]x_f-x_i=V_it+\frac{1}{2}at^2\\20=8t+\frac{1}{2}(9.8)t^2\\4.9t^2+8t-20=0[/tex]

Apply the quadratic formula to solve for time. The negative value does not matter because time cannot be negative, its impossible.

I got a value of t = 1.363 seconds

i think c = p+ r because you firstly have to rearrange the equation so that you isolate the -c. which means you get -c = p-r because you have to change the sign of the r when you switch it. so -c = p-r, but to find c that isn’t minus you need to change the sign on both sides. therefore, the answer should be c = p+r.
