To develop this point we will start by finding the approximate coordinates of the points that were connected at the time of the Pangaea between Brazil and Angola. These coordinates are presented below.
1 . Brazil - Latitude: 18 0 07’ 55.56” S Longitude: 39 0 35’ 14.50” W 2.
Angola - Latitude: 9 0 08’ 50.02” S Longitude: 13 0 02’ 32.11” E
Using a tool for calculating distances between these two points we will notice that its distance is 576,155,570.12 cm
Applying the equation given in the statement we will have to,
200,000,000 years have passed and the movement was previously found, so the speed of travel is,
Therefore the velocity is 2.88 cm per year.
Answer:
Velocity of the projectile just before it will hit the surface is 43.4 m/s
Explanation:
In x direction there is no acceleration
so horizontal velocity of the projectile is always constant
So we have
now in Y direction its motion is free fall motion under gravity
so we have
so we have
