Quiz____?
An amusement park game consists of throwing a quarter into a small bowl. If you win,
you get to take home a giant purple stuffed elephant. The dish is on a shelf that is 0.4
m above the point where the quarter leaves your hand. The horizontal distance
between the bowl and the place where the quarter leaves your hand is 1.8 m. Ignoring
air drag, if you toss the quarter at an angle of 60°, what initial velocity is needed to
bring home the giant purple stuffed elephant? -
Answer✓✓
4.8 m / s
