distance = velocity x time
= 15 m/s x 4 s
= 60 m
363m
If the acceleration was constant (15 + 25) /2 = 20 (time does not figure into the averaging at all!)
it is 10 meters per second straight down
you doing homework???
It is not possible to answer this question without the starting velocity.
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
363m
If the acceleration was constant (15 + 25) /2 = 20 (time does not figure into the averaging at all!)
The object will be moving at 14.7 meters per second. 1.5 seconds X 9.8 meters per second squared(the gravitational constant). This assumes that the object's original velocity is zero.
Velocity is measured in meters/second in the S.I. system.
it is 10 meters per second straight down
.5 meters per second.

Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
19.6 meters per second or about 44mph
