for part b
kinetic energy at ground - F * h = potential energy at top
(1/2) (1) (23)^2 - F (17.8)= 1*9.81*17.8
264.58 - 17.8 F = 174.6
F = 5.05 Newtons I get
A projectile of mass 1.000 kg is shot straight up with an initial speed of 23.0 m/s.
(a) How high would it go if there were no air resistance?
i got 26.99, which is correct
(b) If the projectile rises to a maximum height of only 17.8 m, determine the magnitude of the average force due to air resistance.
i got 4.32.......and it's not right.. help please
