Which force acts opposite of the direction of displacement of the object? I think it would be friction...but could it be spring?

Double check this for me: A player kicks a football with an initial velocity of 3.00 m/s at an angle of 60.0* above the horizontal. What is the horizontal distance traveled by the football? s = vi*t + (1/2)(a)(t2) 0 = 3sin(30)t + 0.5(-9.8)(t2) t = 0.306 s...

A missile launches at a velocity of 30.0 m/s at an angle of 30.0* to the normal. What is the maximum height the missile attains? (((30)*cos(30))^2)/(2*9.8) )

Nevermind... v2-u2=2as Here a = -9.8 m/s 2 Putting in the values 0 - 225 = 2*(-9.8)*S S = 11.5 m That's it right>

That's just sad. So sad.
