A father demonstrates projectile motion to his children by placing a pea on his fork's handle and rapidly depressing the curved tines, launching the pea to heights above the dining room table. Suppose the pea is launched at 7.63 m/s at an angle of 73.0° above the table. With what speed (in m/s) does the pea strike the ceiling 1.90 m above the table?
