A cannon sits upon a cliff on VENUS. It fires a small mallard at some unknown angle. ASSUME: The cannon has a muzzle velocity of 37 m/s                   The cannon has a range of 96 meters                   The cliff is 8 meters above the ground                   The mallard takes 8 seconds to travel to the ground                   The acceleration due to gravity on VENUS is constant but is unknown. DETERMINE: The acceleration due to gravity on VENUS.

A spider moves on a wall along the path shown in the figure. The spider's position and velocity is indicated at t; = 0 and t; = 6.00 seconds. The spider's initial velocity v; = 0.100 m/s is toward the North and final velocity vị = 0.100 m/s is toward the East. Determine the following: a) The x- and y-components of the displacement b) The x- and y-components of the average velocity c) The x- and y-components of the average acceleration. y (m) v = 0.100 m/s 0.350 = 0.100 m/s 0.150- x (m) 0.100 0.400

1) What is the displacement of an object dropped from a height after 1.50 seconds? 2) How long will it take a dropped object to reach the ground if dropped from a height of 1.75 meters? 3) An object is flipped upward at a velocity of 30.0 m/s. At what point in its ascent will its velocity be 2.0 m/s? 4) How long will a coin launched upward at a velocity of 25.0 m/s attain a velocity of 15.0 m/s? 5) A 5-kg rock is dropped from a height of 15.0 m. a) What will be its velocity 0.75 seconds after its drop? b) What will be its velocity at a point 8.0 m from the ground? 6) How high will an object launched upward travel if its initial velocity was 15.0 m/s?
