Homework Statement
A projectile launched straight up at 10 m/s will be in the air for:
A) 1 s
B) 1.4 s
C) 2 s
D) 5 s
Homework Equations
Not sure.
The Attempt at a Solution
I'm honestly not sure what to make of this problem. Since it's freefall, it sounds like we could assume the acceleration to be -10 m/s2. V0 would be equal to 10 m/s and V would equal 0 if it reaches a maximum height. If we need to find t and since we aren't given d, can we use the equation:
v = v0+at?
