Collision Course A useful rule of thumb in piloting is that if the heading from your airplane to a second airplane remains constant, the two airplanes are on a collision course. Consider the two airplanes shown in Figure 4-33. At time t = 0 airplane 1 is at the location (X, 0) and moving in the positive y direction; airplane 2 is at (0, Y) and moving in the positive x direction. The speed of airplane 1 is v1. (a) What speed must airplane 2 have if the airplanes are to collide at the point (X, Y)? (b) Assuming airplane 2 has the speed found in part (a), calculate the displacement from airplane 1 to airplane 2,

- Figure P4.8 shows the motion diagram of two balls, one on the left and one on the right. Each ball starts at a point labeled i. The ball on the left is released and falls straight down. At the same time, the ball on the right is launched horizontally and follows the path shown. a. Use the given coordinate system to write the position of points i, C, E, G, and K in component form for each ball. b. Find the displacement of each ball from i to points C, E, G, and K. c. Compare your answers for the two balls in part (b). What similarities do you notice? FIGURE P4.8 Problems 8 and 26.arrow_forward3-) Murtaza is at the back seat in a convertible car that has a constant velocity of 9.5 m/s on a straight road. He decides to throw a ball up in the air and catches the projectile at the same location on the car but 16 m farther down the road. (a) In the frame of reference of the car, at what angle does Murtaza throw the ball? (b) What is the initial speed of the ball relative to the car? --- 4-) To become airborne, a 2.0g grasshopper requires a takeoff speed of 2.7m/s. It acquires this speed by extending its hind legs through a distance of 3.7 cm. (a) What is the average acceleration of the grasshopper during take-off? (b) Find the magnitude of the average net force exerted on the grasshopper by its hind legs during takeoffarrow_forwardQuestion:- A football kicker is attempting a field goal from 180 m away. The ball is kicked and passes just below the crossbar of the goalpost after a time interval of 20 s. If there is no air resistance and the angle of the kick was 50 degree. i) what was the initial speed of the ball? i) What is the height of the ball after 5 secondsarrow_forward
- A quarterback can run with a speed of vq = 15 mph. He throws a ball with a speed of vb = 35 mph at some unknown angle θ between 30 and 60 degrees, which is measured from horizontal. Neglect air resistance. - a reciever runs past the quarteback ( just beside him) at speed vq. If the quarterback releases his pass at that instant what would be the angle in degrees that he would have to throw the ball for the reciever to catch it?arrow_forwardYou hit a ball with an initial velocity of 25 m/s at an angle of 34° above the horizontal. You are at an initial height of 24 m above the point where the ball lands. What is the magnitude of the velocity of the ball just before it lands? Use a kinematic approach.arrow_forwardDynamics 1. If the resultant force acting on a particle is not zero, the particle will have an acceleration proportional to the magnitudeof the resultant and in the direction of this resultant force.2. Differentiating the velocity with respect to time will obtain ____________ of the particle.3. This is simply obtained from the average velocity by choosing shorter and shorter time intervals Δt and displacementsΔt.arrow_forward
- From the top of a tall building, a gun is fired. The bullet leaves the gun at a speed of 340 m/s, parallel to the ground. As the drawing shows, the bullet puts a hole in a window of another building and hits the wall that faces the window. Using the data in the drawing, determine the distances (a) D and (b) H, which locate the point where the gun was fired. Assume that the bullet does not slow down as it passes through the window. Show all steps please.arrow_forwardJeff throws a ball straight up at an angle of 90°. For which situation is the total velocity zero? A. At the top of the path B. No where along the path C. Just after it reaches the top of its path D. Just before the top of the path E. Just before it hit the groundarrow_forwardFinding the Actual Speed and Direction of an Aircraft AnAirbus A320 jet maintains a constant airspeed of 500 mphheaded due west.

- A quarterback throws a football toward a receiver with an initial speed of 11 m/s at an angle of 30° above the horizontal. At that instant the receiver is 15.0 mfrom the quarterback. (a) In what direction should the receiver run in order to catch the football at the level at which it was thrown? The receiver should run in the direction opposite to that in which the football is traveling Or The receiver should run in the direction the football is traveling ? (b) With what constant speed should the receiver run in order to catch the football at the level at which it was thrown? Find m/sarrow_forwardA man drives a motorcycle off a horizontal roof to a neighboring rooftop to another building. The second roof is 6 meters lower and 10 meters away. Ignoring air resistance, how long is the motorcycle in the air? What is the minimum initial speed needed to reach the other building? What direction is the man's velocity point relative to the horizontal roof just before he lands? Assume initial speed found in earlier answer.arrow_forwardTy Ridlegs boards a paddle boat and heads the boat westward directly across a river. The river flows south at 48 cm/s. Ty paddles the boat with a speed of 98 cm/s. a. Determine the resultant velocity of the boat - both magnitude and direction.b. If the river is 22 m wide at this location, then how much time does it take Ty to cross the river? Assume that Ty keeps his paddle boat headed west.c. How far downstream will Ty be when he reaches the other side of the river?arrow_forward
