represents the vertical distance s that an object travels in t seconds, where u represents the initail velocity of the object an dv represnts the velocity of the object at the end of t seconds. Find the velocity of the ball at the end of 1.5 seconds

:
Solve the formula for v, and plug and chug.

u=53, s=42, t=1.5 (units for v:ft/s)

v=20.6666667 ft/s
v=2.1x10 ft/s rounding off to significatant digits. I don't know how much that matters to you.
Happy Calculating!!!
