1.Calculate the height of a precipice by taking 2.35s. A person on the edge of a precipice throws a rock directly upward with an initial velocity of 8.00 m / s. Determine the height of the cliff if the rock takes 2.35s to reach the ground. Hint: Draw the situation and place the coordinate system where the rock ends.

2. A projectile is launched from the ground with an initial velocity of 50.0 m / s at an angle of 30.00. Calculate the maximum height of the projectile. Hint: Put the coordinate system where the projectile begins. What is the condition for maximum height?
