To solve the problem of how long the baseball takes to reach its maximum height when tossed upwards with an initial speed of 12 m/s, we can use the equations of motion. Here’s a step-by-step solution: ### Step 1: Identify the known values - Initial velocity (u) = 12 m/s (upwards) - Final velocity (v) at maximum height = 0 m/s (the ball stops momentarily at the peak) - Acceleration (a) = -g = -9.8 m/s² (the negative sign indicates that gravity is acting downwards against the motion of the ball) ### Step 2: Use the equation of motion ...
