- Sofia is playing a game with her friend, Kara, where she throwsM&M candies at Kara and Kara catches the M&M’s in hermouth. They begin standing 1.75 meters apart from eachother. Sofia throws the M&M at an angle of 60 degrees abovethe horizontal with a speed of 4.13 m/s. Kara’s mouth is145 cm above the ground when she catches the M&M. Whatheight above the ground did the M&M leave Sofia’s hand?Hint: Remember, even though the motion in the horizontaldirection is independent of the motion in the vertical direc-tion, they share the same time.Viy=? 30 Va-326m/s A rocket is fired at an angle of 30° above the horizontal.
