Answer:
<u>954.4m/s</u>
Explanation:
For a free falling object,it has constant acceleration and a changing velocity.
By using the velocity-time formula, the velocity can be obtained.
The height the rock travelled is the distance.
From,
Velocity (v) = Distance (d) / Time(t)
v = 3245m/3.4s
v = <u>954.4m/s</u>
That js the answer I got. Hope it's right.
Answer:
usually its because they dont wanna talk
Explanation:
I know what thats like. Either that or they don't trust you. It could be something personal or they just dont wanna talk. But i wouldn't push. Just let them talk if they want to
For the first part of the trip:
we have velocity = 960 km/hr and distance = 2250 km
velocity = distance / time
time1 = distance / velocity = 2250 / 960 = 2.34375 hours
For the second part of the trip:
we have velocity = 805 km/hr and distance = 1320 km
velocity = distance / time
time2 = distance / velocity = 1320 / 805 = 1.63975 hours
For the total trip:
we have:
total distance covered = 2250 + 1320 = 3570 km
total time taken = 2.34375 + 1.63975 = 3.9835 hours
average velocity = total distance / total time
average velocity = 3570 / 3.9835 = 896.1968 km/hr
Answer:
travels along a curve due to uniform gravity
Explanation:
General relativity
The theory was developed by Albert Einstein , it is the theory of gravitation , according to which , the gravitation effect which is observed between the masses , is the resultant of their warping of the space time .
In general relativity , the equivalence principle is the equivalence of inertial gravitational mass .
According to which , the light bends due to gravitational forces ,therefore , the light travels along a curve because of uniform gravity .
