e) determine the magnitude of the acceleration of the projectile midway on its trajectory 

**Projectile Motion Problem**

A 2.80-kg projectile is launched horizontally with an initial speed of 52.0 m/s (see the figure above). The projectile lands 5.70 s later. Ignore air resistance.

**Tasks:**

(a) Determine the initial height of the projectile, \( h \).

- Answer: _______ m

(b) Determine the range of the projectile, \( R \).

- Answer: _______ m

(c) Determine the speed of the projectile just before it lands.

- Answer: _______ m/s

(d) Determine the angle of the velocity of the projectile below the horizontal just before it lands.

- Answer: _______ degrees

**Diagram Explanation:**

The diagram shows a projectile path with an initial horizontal launch. The height \( h \) is the vertical distance from the launch point to the landing point. The range \( R \) is the horizontal distance traveled by the projectile. The trajectory is a downward curved path indicating motion under gravity. The motion suggests it starts horizontally and curves downwards until it hits the ground.
