Question 1 of 5 > Consider the scenario: ' ,. 1- " ' " "' a. i. I ' ~ A projectile is red over level ground with an initial speed of 'v' '3' HI] = 394.0 mJ's, at an angle of I9 : 72.3\" with respect to f \\ the horizontal. Which equation would be most useful for calculating the horizontal range R that the projectile will travel? OR=3 0) Q R = Basinzw) 23 O R : Usin) g OR=m+mMgm Question 2 of 5 > A projectile is launched from ground level with an initial speed of 41.5 mfs at an angle of 32.1\" above the horizontal. It strikes a target in the air 1.66 5 later. What is the horizontal distance from where the projectile was launched to where it hits the target? What is the vertical distance from where the projectile was launched to where it hits the target? Question 3 of 5 > You stand 17.5 m from a wall holding a tennis ball. You throw the tennis ball at the wall at an angle of 34.5\" from the ground with an initial speed of 30-5 mfs. At what height above its initial position does the tennis ball hit the wall? Ignore any effects of air resistance. Question 4 of 5 ) Bob has just nished climbing a sheer cliff above a beach, and wants to gure out how high he climbed. All he has to use, however, is a baseball, a stopwatch, and a friend on the beach below with a long measuring tape. Bob is a pitcher and he knows that the fastest he can throw the ball is about {JD 2 32.1 mfs. Bob starts the stopwatch as he throws the ball {with no way to measure the ball's initial trajectory), and watches carefully. The ball rises and then falls, and after t. = 0310 s the ball is once again level with Bob. Bob cannot see well enough to time when the ball hits the ground. Bob's friend then measures that the ball landed at = 127 m from the base of the cliff. How high up is Bob, if the ball started exactly 2 m above the edge of the cliff? Question 5 of 5 An airplane releases a ball as it flies parallel to the ground at a height of h = 255 m as shown in the figure. If the ball lands on the ground a horizontal distance equal to the height h from the release point, calculate the speed v of the plane. Neglect any effects due to air resistance, and use g = 9.81 m/s for the acceleration due to gravity. U = m/s
