First find the direction velocity
Vo =
tan θ = vy/vx = 10/30 = 1/3
so, sin θ = 1/√10 = √10/10
and time to reach further point is same with how long the ball in the air
Sorry for bad english (from Indonesian)
Answer:
It will take 30 seconds to reach the ground, and it will be travelling at 294 m/s when it does so. This means that its average velocity was 147 m/s.
Explanation:
Since the intial velocity of a dropped object is 0, we can make this the equation:
The final velocity can be calculated with the formula:
Once again, since there is no initial velocity:
Since the intial velocity is 0, the average vertical velocity is 294/2=147 m/s.
Hope this helps!
Answer:
8.75 m/s^2
Explanation:
initial speed, u = 300 m/s
final speed, v = 400 m/s
distance, h = 4 km = 4000 m
Let a be the acceleration of the plane.
Use third equation of motion
a = 8.75 m/s^2
Thus, the acceleration of the plane is 8.75 m/s^2.
E. Acceleration is the answer
Rocks and Continental shapes because if you put the continents together they will be very close to match and if you find a fossil (like south america) and a fossil in africa they will be the same animals . <span />
