Question

+10 m/s2 zero -10 m/s2 +5 m/s2 -5 m/s2 A projectile is fired from the origin (at y = 0 m) as shown in the figure. The initial velocity components are V0x = 270 m/s and V0y = 57 m/s. The projectile reaches maximum height at point P, then it falls and strikes the ground at point Q. In the figure, the y-component of the acceleration of the shell at point P is closest to: A projectile is fired from the origin (at y = 0 m) as shown in the figure. The initial velocity components are = 270 and = 57 . The projectile reaches maximum height at point P, then it falls and strikes the ground at point Q. In the figure, the y-component of the acceleration of the shell at point P is closest to: +10 m/s2 zero -10 m/s2 +5 m/s2 -5 m/s2

Explanation / Answer

y component of acceleration = g = 9.81 m/s^2 in the downward direction

closest to 10 m/s^2
