A pumpkin with a mass of 3.3 kg is launched from a catapult at an initial height of 3.8 m off the ground, with an initial speed
dimaraw [331]

Answer:

11.2m

Explanation:

Suppose the pumpkin is launched vertically and the speed of 13.9 m/s is absolutely vertical. As the pumpkin rises up, its kinetic energy is converted to potential energy, let the reference point be the round, we can create the following equation from the law of energy conservation:

E_1 + P_1 = E_2 + P_2

0.5mv_1^2 + mgh_1 = 0.5mv_2^2 + mgh_2

we can substitute g = 9.8m/s^2, v_1 = 13.9m/s, v_2 = 0.5v_1 = 0.5*13.9 = 6.95 m/s, h_1 = 3.8

We can also divide both sides by m and 0.5

13.9^2 + 2*9.8*3.8 = 6.95^2 + 2*9.8*h_2

19.6h_2 = 219.3875

h_2 = 11.2m
