10.9 m/s
3.61 meters
100 meters per 15.00 seconds = 14.91 mph
100 meters / 11 seconds = 20.336 mph (rounded)
The initial velocity is 10 meters/sec and is thrown up against the gravitational pull of the earth. This means that the ball is experiencing a deceleration at the rate of 9.8 meters/sec/sec to bring its final velocity to zero. v^2 - u^2 = 2gs where u is the initial velocity, v the final velocity, g is the acceleration or deceleration, and s is the distance traveled. 0^2 - 10^2 = 2 x (-9.8) x s -100 = -19.6s 100 = 19.6s s = 100/19.6 = 5.102 meters Now v = u + gt where v is the final velocity, u is the initial velocty, g is the acceleration or deceleration, and t is the time. When the ball is thrown up with 10 meters/sec velocity it is acted upon by the deceleration of gravity until its velocity becomes zero. So 0 = 10 - 9.8t or 9.8t = 10 t = 1.020 seconds The time for the ball to go up is 1.020 seconds and the same time is taken for the ball to come back for a total of 2.040 seconds.
If an object is travelling 100 meters in 1400 seconds, then it is travelling (100 / 1400) or about 0.0714 meters per second.
If you traveled 100 meters in 30 seconds, then you would be traveling at 3.333... meters per second, or 200 meters per minute, or 12 kilometers per hour (7.45 miles/hour).
Half a second every metre.
3.61 meters
(100,000 meters/hour) x (0.13 second) / (3,600 seconds / hour) = 3.6111 meters (rounded, repeating)
6.66 meters per second.
One example problem of speed and velocity would be 'What is the speed of a sailboat traveling 100 meters in 180 seconds?' You can use a calculator to solve these types of problems.
100 meters per 15.00 seconds = 14.91 mph
Acceleration = (Change in speed)/(Time) a = (v-u)/t = (500-1000)/5 = -500/5 = -100 Acceleration is -100 ms-2
100 meters / 11 seconds = 20.336 mph (rounded)

That's 0.1 km per second for 8x3600 seconds, equals 2880 km
