Projectile motion
H2 Physics · JC 2 · Hard · Projectile motion
A ball is thrown horizontally from a cliff and lands 12 m below the point of release after 1.6 s. Take downward as positive. Using the constant-acceleration equation for vertical motion, calculate the vertical component of its velocity just before it hits the ground. Take gravitational acceleration as 9.81 m s⁻².
- 15.7 m s⁻¹ downward
- 9.81 m s⁻¹ downward
- 6.13 m s⁻¹ downward
- 25.5 m s⁻¹ downward
