How high would this ball go if it were thrown straight upward at speed v0?Ī 3600 kg open railroad car coasts along with a constant speed of 11.0 m/s on a level track. How high would this ball go if it were thrown straight upward at speed v0?Ī ball is thrown upward at a speed v0 at an angle of 52.0˚ above the horizontal. 424,Ī ball is thrown upward at a speed v0 at an angle of 57.0˚ above the horizontal. When leaping at an angle of 58.0 degrees above the horizontal, some of the tiny critters have reached a maximum height of 58.7 cm above the level ground. The froghopper, Philaenus spumarius, holds the world record for insect jumps. Sand is falling from a rectangular box container whose base measures 40 inches by 20 inches at a constant rate of 300 cubic inches per minute. I figured out that part "A" is -3/8, but i can't figure out part 2, a or b. What was the initial speed of the bottle cap, just after leaving the rubber band? The cap travels a horizontal distance of 1.30 m in 1.40 s. What was the initial speed of the bottle cap, just after leaving the rubber band?Ī child uses a rubber band to launch a bottle cap at an angle of 40.0° above the horizontal. The cap travels a horizontal distance of 1.30 m in 1.60 s. Ī child uses a rubber band to launch a bottle cap at an angle of 35.5° above the horizontal. how many square centimetres of paper have been used to make the box. WhatĪ paper box without a lid is 25 cm long. What is its speed after 1.9 s? Answer in units of m/s. It is then given a horizontal acceleration of 2.3 m/s2 and a downward acceleration of 1.6 m/s2. Calculate the mechanical work done by theĪ particle has an initial horizontal velocity of 1.8 m/s and an initial upward velocity of 4.7 m/s. The force of friction on the wagon is 34 N. She exerts a force of 80.0 N at an angle of 30.0 above the horizontal while she moves the wagon 12 m forward. Find the height of the racquet ball when it leftĪ box weighing 450 Newtons is pulled along a level floor at an angle of 30 degrees with the floor.If the force of the rope is 260 Newtons.What is the coefficient of sliding friction for the surface?Ī child pulls a wagon by the handle along a flat sidewalk. When the ball hits the court, it is a horizontal distance of 1.94 m from the racquet. What must be (a) the magnitude and (b) the direction of the third force, such that the objectĪ racquet ball is struck in such a way that it leaves the racquet with a speed of 4.8 m/s in the horizontal direction. Another has a magnitude of 45.9 N and is directed due west. One force has a magnitude of 62.6 N and is directed due north. If the box’s dimensions are equal and the length is 3 feet long, what is the volume of the box in cubic feet? A. What is the width of the box? –10 in 8 in (my answer?) 20 in 40 in *ĭaisy is shipping a package to her daughter, Molly. How many kilograms of mass can be loaded into the box before it will sink in a freshwater lake?Ī box shaped like a rectangular prism has a height of 17 in and a volume of 2,720 in³ The length is 4 inches greater than twice the width. If the side lengths are all the same, what is the length of each side of the box? Hint: V = s^3Ī rectangular box of negligible mass measures 5m long,1m wide and 0.5m high. The box she will use has a volume of 216 cubic inches. Find the volume of the largest box that can be made this wayġ5. find the height in centimeters, of the box that uses the least amount of materialĪ box is to be made of a piece of cardboard 9 in ² by cutting equal squares out of the corners and turning up the sides. The volume of an open topped box with a square base is 245 cubic centimeters. Determine the magnitude of applied force when teh ramp is frictionless and when the coefficient A 90Kg box is pushed by a horizontal force F at constant speed up a ramp incined at 28 degrees. ![]()
