An object is projected from horizontal ground at a velocity of magnitude u and angle θ to the horizontal. It hits the ground at a time t after it is projected. Assume air resistance is negligible. Which statement does not describe the motion of this object?
- AThe horizontal component of the object's velocity is constant and has the value ucosθ.
- BThe horizontal distance travelled by the object is tucosθ.
- CThe time taken for the object to reach maximum height is t/2.
- DThe vertical component of the object's velocity is constant and has the value usinθ.
