Answer: Got It!
<em>Explanation: </em>let s = speed at launch
v = 0 at top = s sin 63 - g t
so at top
t = s sin 63/g = .0909 s
h = 13.6 = s sin 63 t - 4.9 t^2
13.6 = .081s^2 - .0405 s^2
s^2 = 336
s = 18.3 m/s
0 0
Answer:
Explanation:
Let's use the conservation of momentum to solve it.
(1)
- The total initial momentum will be:
- The total final momentum will be:
, but as they stick together after the collision, v1f = v2f = vf.
So we can rewrite (1), using the above information:
Finally, the magnitude of the velocity of the wreckage of the two cars immediately after the collision is:
