Two marbles are launched at t = 0 in the experiment illustrated in Figure 4-29. Marble 1 is launched horizontally with a speed of 4.20 m/s from a height h = 0.950 m. Marble 2 is launched from ground level with a speed of 5.94 m/s at an angle θ = 45.0° above the horizontal. (a) Where would the marbles collide in the absence of gravity? Give the x and y coordinates of the collision point. (b) Where do the marbles collide given that gravity produces a downward acceleration of g = 9.81 m/s2 ? Give the x and y coordinates.

Introduction to Electrodynamics
- A stone is thrown at a cliff with a height of h. If the stone is thrown with an initial speed of 42 m/s at an angle θ=60° and hits the cliff at A 5.5 seconds later, determine the speed of the stone when it hits A. Use g = 10 m/s/s.arrow_forwardA hitter strikes a baseball so that it leaves the bat at speed v0= 37.0 m/sat an angle θ 0= 53.1°. (a) Find the distance of the ball from the origin and its velocity (magnitude and direction) at t = 2.00 s. (b) Find the time when the ball reaches the highest point of its flight, and its height at this time.(c) Find the range of the ball.arrow_forwardVhas Thed is standing on a bridge. He is at a height 83.6 m above the water below. Suddenly he received a call from his cell phone that makes him mad and throws his phone horizontally off the bridge with a speed of 25.7 m/s. How far does the cell phone travel horizontally before hitting the water? Draw an Illustration.arrow_forward
- During the siege of Constantinople that led to its conquest by the Ottomans in 1453, the Hungarian engineer Orban built a set of bombards (primitive cannon) to throw enormous stones at the city to breach its walls. The largest of these could throw a 300 kg stone a distance x = 2 km. Assume that the stone was launched at an angle of 0 = 45 degrees above the horizontal; in the absence of air resistance, this gives the largest range. a) What speed did the stone have to be launched at to achieve this range? b) How long was the ball in the air? c) How fast was the ball traveling at the apex of its flight?arrow_forwardIn a computer game, an airplane starts at (1 00,400) (in cm) on the curve y = 3,00 + x-1.50 and moves with a constant horizontal velocity of 1.80 cm/s. What is the plane's velocity after 0.600 s? Begin by finding expressions for the x- and y-components of the velocity Vy and Vy (Type expressions using t as the variable) ***arrow_forwardTwo friends are playing catch. They both are about the same height so the release height of the ball when thrown and the height of the catch are both 1.75 meters above the ground. The friend on the right throws the ball at a speed of 15 m/s at an angle of 33° above the horizontal. Assume you can ignore air resistance for this problem. (1) What are the horizontal and vertical components of the initial velocity of the ball? (2) How far away should the second friend stand to catch the ball (at a height of 1.75 m above the ground)? 1: You'll first need to solve for the time the ball is in the air. 2: If you don't know how to solve for time, then pick a value for the time the ball is in the air and perform your remaining calculations using that value for timearrow_forward
- A physics student stands on a cliff overlooking a lake and decides to throw a tennis ball to her friends in the water below. She throws the tennis ball with a velocity of 25.5 m/s at an angle of 38.5° above the horizontal. When the tennis ball leaves her hand, it is 10.5 m above the water. How far does the tennis ball travel horizontally before it hits the water? Neglect any effects of air resistance when calculating the answer. horizontal distance:arrow_forwardYou fire a ball with an initial speed v0 at an angle ϕ above the surface of an incline, which is itself inclined at an angle θ above the horizontal (Figure 1). (a) Find the distance, measured along the incline, from the launch point to the point when the ball strikes the incline. (b) What angle ϕ gives the maximum range, measured along the incline? Ignore air resistance. What is the initial x -component of the ball's initial velocity? Express your answer in terms of the variables v0 , θ, ϕ. What is the initial y -component of the ball's initial velocity? Express your answer in terms of the variables v0 , θ, ϕ. You'll need to write an equation that relates x and y for points along the incline. What is this equation? Express your answer in terms of the variables x , θ, and appropriate constants, if needed.arrow_forwardFlg. 4-51 Problem 91.
