Question
A student stands at the edge of a cliff and throws a stone over the edge at an angle 0
above the horizontal. Ignoring the effects of air resistance, which of the following
statements must be true? (There may be more than one correct answer).
A plot of the horizontal position x vs. time t will have a constant and positive
slope
The horizontal range of the stone equals vo2sin(20)/g
There is no point in the stone's motion in which the stone's speed matches its
initial speed.
A plot of the vertical velocity component vy vs. time t will have a constant and
negative slope
When the stone reaches its maximum height, its velocity will be zero

Expert Solution
Step 1

When a particle is thrown obliquely near the Earth's surface, it moves along a curved path. Such a particle is called a projectile and its motion is called projectile motion. The acceleration of a projectile is almost constant and is equal to the acceleration due to gravity, g.

The horizontal component of acceleration in a projectile motion is zero. Only the vertical downward acceleration due to gravity acts on the projectile.
