A rock is thrown at a window that is located 18.0 m above the ground at an angle of 40.0° above horizontal angle. The rock is thrown from a height of 2.00m above the ground with a speed of 30.0 m/s with no air resistance. If the rock strikes the window on its upward trajectory, from what horizontal distance from the window was it released? answers: 27.3m, 53.2m, 29.8m, 48.7m, 71.6m ?

Question

A rock is thrown at a window that is located 18.0 m above the ground at an angle of 40.0° above horizontal angle. The rock is thrown from a height of 2.00m above the ground with a speed of 30.0 m/s with no air resistance. If the rock strikes the window on its upward trajectory, from what horizontal distance from the window was it released?

answers: 27.3m, 53.2m, 29.8m, 48.7m, 71.6m ?

Expert Solution
Step 1

Given data

The location of the window from the ground is Sy = 18 m

The rock is thrown at an angle of θ = 40°

The initial speed of the rock is u = 30 m/s

The initial height from where rock is thrown is yo = 2 m
