Answer:
Given:
Initial velocity of the asteroid, v = 19.9 km/s = 19900 m/s
(since, 1km = 1000 m)
Final velocity of the asteroid, v' = - 18.3 km/s = -18300 m/s
time period, T = 1.97 years
Solution:
(a). Total change in velocity, :
= v' - v
= - 18300 - 19900 = - 38200 m
here, negative sign is indicative of the fact that the motion of the asteroid is in the downward direction.
(b) Asteroid's average acceleration, a:
a =
a =
a =
Here, the negative sign is the indication of deceleration of the asteroid in the downward direction.
Since it was dropped, it should be the speed of gravity which is 9.8 meters/second
Answer:
.5m per second to the west
Explanation:
distance divided by time
