Question 7You throw a handful of different coins up and forward and watch them arc through space. They leave your hand at the same moment and with the same starting velocity. Neglecting any effects due to air, where and when do those coins hit the level ground in front of your feet? [Note: air can significantly affect fast-moving coins. If you want to test your answer experimentally, be careful to minimize those air effects. Also, be safe!]1 pointAll the coins hit the ground at the same time and at the same distance from your feet.The heavier coins hit the ground before the lighter coins, but they all hit the ground at the same distance from your feet.The heavier coins hit the ground before the lighter coins and they hit the ground farther from your feet than do the lighter coins.All the coins hit the ground at the same time, but the heavier coins hit the ground farther from your feet than do the lighter coins.

You drop a coin from the CN tower. Air resistance is not negligible. Describe the motion of the coin. It accelerates at -g until the coin reaches terminal speed, and then has constant speed. It accelerates at -g until it hits the ground. It falls at constant speed until it hits the ground. Its acceleration is initially -g, but its magnitude gradually decreases to zero as the coin falls.

why does the first coin reach the floor first instead of landing both at the same time

You've learned to juggle 4 balls at once here on Earth. During a visit to the moon, where the acceleration due to gravity is about 1/6th its Earth value, you decide to try juggling those same 4 balls. You find that, on the moon, each ball has ________________.1 pointless weight and falls more slowly than on Earth. It undergoes the same acceleration as on Earth when exposed to the same force as on Earth.less weight and falls more slowly than on Earth. It accelerates more rapidly than on Earth when exposed to the same force as on Earth.the same weight, but falls more slowly than on Earth. It accelerates more slowly than on Earth when exposed to the same force as on Earth.the same weight and falls at the same rate as on Earth. It accelerates more slowly than on Earth when exposed to the same force as on Earth.

A coin placed on a rotating table just slips when it is placed at a distance of  1 cm from the center. If the angular velocity of the table in halved, it will just slip when placed at a distance of _________ from the centre :

orWatch a videoIf you flip a coin 12 times, what is the best prediction possible for the number of times it will land on tails?
