Some plants disperse their seeds when the fruit splits and contracts, propelling the seeds through the air. The trajectory of th

ese seeds can be determined with a high-speed camera. In an experiment on one type of plant, seeds are projected at 20 cm above ground level with initial speeds between 2.3 m/s and 4.6 m/s. The launch angle is measured from the horizontal, with + 90° corresponding to an initial velocity straight up and – 90° straight down.
About how long does it take a seed launched at 90° at the highest possible initial speed to reach its maximum height? Ignore air resistance. (a) 0.23 s; (b) 0.47 s; (c) 1.0 s; (d) 2.3 s.

if the velocity of a body changes from 13m/s to 30m/s while undergoing constant acceleration,what's the average velocity of the
Bess [88]

       Average speed = (1/2) (beginning speed + ending speed)

                               = (1/2)        ( 13 m/s  +  30 m/s )

                               =    (1/2)        ( 43 m/s )

                               =        21.5 m/s

Talia is on a road trip with some friends. In the first 2 hours, they travel 100 miles. Then they hit traffic and go only 30 mil
emmainna [20.7K]
Since Speed, V = Distance/Time
Average speed = Total Distance/Total Time

From the given data, Total Distance = 100 + 30 + 75 miles
and Total Time = 2 + 1 + 1 hours

Average Speed = 205/4
Average Speed = 51.25 mph ( or 51mph to the nearest whole number)
