Question

Given the equation below, which description best fits the physical situation? -99. 6 m - (-40. 0 m/s) (2. 00 s) -1/2 (9. 80 m/s2) (2. 00 s) 2 A projectile's displacement two seconds after being fired downward with a speed of 50. 0 m/s. A projectile's displacement two seconds after being fired downward with a speed of 40. 0 m/s. A projectile's displacement two seconds after being fired downward with a speed of 30. 0 m/s. A projectile's displacement two seconds after being fired downward with a speed of 60. 0 m/s. A projectile's displacement two seconds after being fired downward with a speed of 80. 0 m/s.
