(a) To find the maximum height attained by Wolverine during the flight, we first need to find the vertical component of the initial velocity. This can be calculated using the equation: v_iy = v_i * sin() where: v_iy = vertical component of the initial velocity v_i = initial velocity = 22.6 m/s = angle of projection = 24.7 v_iy = 22.6 m/s * sin(24.7) = 9.4 m/s Next, we use the equation for the maximum height in projectile motion: H_max = (v_iy^2) / (2g) + d where: H_max = maximum height v_iy = vertical component of the initial velocity = 9.4 m/s g = acceleration due to gravity = 9.8 m/s^2 d = initial height = 2.20 m H_max = (9.4 m/s)^2 / (2*9.8 m/s^2) + 2.20 m = 4.5 m + 2.20 m = 6.7 m So, the maximum height attained by Wolverine during the flight is 6.7 m. (b) To find Wolverine's speed the instant before he hits the ground, we use the conservation of energy principle. The total mechanical energy at the highest point (potential energy) will be equal to the total mechanical energy just before hitting the ground (kinetic energy). Potential energy at the highest
