WebDec 20, 2024 · Solution. The acceleration vector of the enemy missile is. ae(t) = − 9.8ˆj. Integrating, we get the velocity vector. ve(t) = v1ˆi + (v2 − 9.8t)ˆj. Setting t = 0 and using the initial velocity of the enemy missile gives. ve(t) = − 30ˆi + (3 − 9.8t)ˆj. Now integrate again to find the position function. WebSince ∫ d d t v ( t) d t = v ( t), the velocity is given by v ( t) = ∫ a ( t) d t + C 1. 3.18 Similarly, the time derivative of the position function is the velocity function, d d t x ( t) = v ( t). Thus, we can use the same mathematical manipulations we just …

WebAverage speed is a scalar, so we do not include direction in the answer. We can check the reasonableness of the answer by estimating: 5 meters divided by 2 seconds is 2.5 m/s. Since 2.5 m/s is close to 2.9 m/s, the answer is reasonable. This is about the speed of a brisk walk, so it also makes sense. WebJul 15, 2010 · Using drudkh's example cited above and using Einstein's velocity addition formula, closure speed between a particle moving to the right at v and light coming from the right and moving left at c would still be c. ... you have to use the velocity addition formula to get (v+c)/(1+vc/c 2). If you want to calculate the closing speed, you just add ... horizon therapeutics press release
