Here's how to solve part (a) of the problem. Given: • Initial velocity, u = 0 m/s (assuming the technician starts from rest) • Height, h = 80 m • Acceleration due to gravity, g = 10 m/s^2 We need to find the time, t. Step 1: Identify the appropriate kinematic equation. To find the time when initial velocity, displacement, and acceleration are known, we use the equation: h = ut + (1)/(2)gt^2 Step 2: Substitute the given values into the equation. 80 m = (0 m/s)t + (1)/(2)(10 m/s^2)t^2 Step 3: Simplify the equation and solve for t^2. 80 m = 0 + (5 m/s^2)t^2 80 m = (5 m/s^2)t^2 t^2 = 80 m5 m/s^2 t^2 = 16 s^2 Step 4: Calculate t by taking the square root. t = sqrt(16 s)^2 t = 4 s The time it takes for the technician to hit the ground is 4 s. That's 2 down. 3 left today — send the next one.
