Detailed explanation-1: -The horizontal range, , of a projectile launched from the same initial and final vertical displacement can be calculated as = 2 ( ) ( ) , s i n c o s where is the initial speed of the projectile, is the launch angle measured above the horizontal, and is the gravitational constant.
Detailed explanation-2: -FALSE-A projectile has a constant horizontal velocity. The vertical velocity will change by 9.8 m/s each second.
Detailed explanation-3: -The magnitudes of the components of velocity v → v → are v x = v cos and v y = v sin , v x = v cos and v y = v sin , where v is the magnitude of the velocity and is its direction relative to the horizontal, as shown in Figure 4.12.
Detailed explanation-4: -Formula : x = V x 0 * t . Enter the unknown value as ‘ x ‘ Initial Horizontal Velocity ( V x 0) = m / s. Time (t) = = s. Horizontal Displacement at Time ( x ) = m. Answer =
