Time in air Five balls are all at the same height near the surface of Earth. One is dropped from rest but the others are launched horizontally. Using the information given in the table below, state how long it will take for each ball to fall to the ground after being launched. Ignore air drag. Ball 1 Ball 2 Ball 3 Ball 4 Ball 5 0.2 18 (m/s) At...

009 (part 1 of 3) 10.0 points A ball of mass 0.4 kg, initially at rest, is kicked directly toward a fence from a point 20 m away, as shown below The velocity of the ball as it leaves the kicker's foot is 16 m/s at angle of 47° above the horizontal. The top of the fence is 4 nm high. The ball hits nothing while in flight and ates air resistance is...

1. When you drop a ball it accelerates downward at 9.8 m/s. If you instead throw it downward, then its acceleration immediately after leaving your hand, assuming no air resistance, is A. 9.8 m/s2 B. More than 9.8 m/s C. Less than 9.8 m/s D. Cannot say, unless the speed of the throw is given. 2. A heavy rock and a light rock in free fall (zero air resistance) have...

Hi I need help with the following problems: 1.A ball is thrown horizontally from the roof of a building 45.0 m tall and lands 24.0 m from the base. What was the ball’s initial speed? 2.A football is kicked at ground level with a speed of at an angle of 36.9º to the horizontal. How much later does it hit the ground? How height does it rise? What is its range? 3.A projectile is fired with an initial speed of...

is ball on Moon, where the acceleration due to gravity is 1/6(g -9.8) and air resistance is negligible, is hit directly upward and returns to the same level 85 s later, (a) How high above its origjinal point did the ball go? (b) How fast it moving just a after it was hit? 7. Two train cars are on a straight, horizontal track. The car A starts at rest and is put in motion with a constant acceleration of 2.00...
