4. There are two frogs named Eroggy and Jumpy. They jumped from the top of a vertical cliff. Froggy just drops and reaches the ground in 3.50 s, while Jumpy jumps horizontally ((bida bida siya, char! Hahall with an initial speed 95 cm/s. a. How far from the base of the cliff will Jumpy hit the ground? b. How high is the vertical cliff? c. If Jumpy jumps with an angle of 30 degrees with respect to the horizontal, what should be its initial velocity for it to land on the same spot as he did when he jumped horizontally?

On planet #3, you fire a projectile horizontally from the edge of a vertical cliff 69.9 m above the ground, with an initial speed of 59.8 m/s. The projectile lands 67.2 m away from the base of the cliff. What is the value of g for planet #3?   a. 183.63 m/s^2   b. 110.71 m/s^2   c. 55.35 m/s^2   d. 49.18 m/s^2 2.  On planet #4, you fire a projectile from the ground at an initial speed of 20.0 m/s at an angle of 43.1 degrees above the horizontal. The projectile lands 78.7 m away from the launch point. What is the value of g for planet #4?   a. 3.5 m/s^2   b. 309.0 m/s^2   c. 211.6 m/s^2   d. 5.1 m/s^2
