After an object has fallen for 3.5seconds its speed is 22.5m/s. What is its speed after 5s?The speed of an object is directly proportional to the time it has fallen.?
v = v0 + a*t
assuming it started from rest means:
22.5 m/s = a * 3.5s
-%26gt; a = 6.43 m/s^2
-%26gt; vf = (6.43 m/s^2)*(5s) = 32.1 m/s
cheersThe speed of an object is directly proportional to the time it has fallen.?
if the speed is directly proportional, then the speed is 32.143m/s given that there is no terminal velocity fir the object
and you wonder why you don't go to the prom
