With the X Axis Horizontal and the Y Axis Vertically $\Delta$

question 17

Multiple Choice

With the x axis horizontal and the y axis vertically upward,the change in the horizontal component of velocity, $\Delta$ v_x,and the change in the vertical component of velocity, $\Delta$ v_y,of a projectile are related to the time since leaving the barrel, $\Delta$ t,as

• A)\(\Delta\)v_x = 0;\(\Delta\)v_y = 0.
• B)\(\Delta\)v_x = g\(\Delta\)t;\(\Delta\)v_y = 0.
• C)\(\Delta\)v_x = 0;\(\Delta\)v_y = g\(\Delta\)t.
• D)\(\Delta\)v_x = 0;\(\Delta\)v_y = -g\(\Delta\)t.
• E)\(\Delta\)v_x = g\(\Delta\)t;\(\Delta\)v_y = -g\(\Delta\)t.
