Chapter 3, Problem 67PE
An ice hockey player is moving at 8.00 m/s when he hits the puck toward the goal. The speed of the puck relative to the player is 29.0 m/s. The line between the center of the goal and the player makes a 90.0° angle relative to his path as shown in Figure 3.65. What angle must the puck's velocity make relative to the player (in his frame of reference) to hit the center of the goal?

He visualizes Sid as a hunk of meat and begins to chase him frantically around the ground. First, Sid darts 50.0 meters at 35.0° NoW and then turns abruptly and races 40.0 m S. If Manny ran from where they were originally standing to where Sid ended up, how far and in what direction would Manny have to run to break up the fight? Use the triangle method to solve this. Should you use the component method, I will award zero points. I know the answer I just don’t know how to get it.

- Trachecktory. Two cannonballs, aptly named a and B, were launched on level ground. a was launched with a velocity of 18.0 [m/s] at 36° with respect to the ground while B was launched with a velocity of 17.6 [m/s] at 48° with respect to the ground. What can you say about a and B's range and time of flight? O a and B have the same range; a has a larger time of flight. O a and B have the same range; B has a larger time of flight. O a and B do not have the same range; B has a larger time of flight. O a and B do not have the same range; a has a larger time of flight.arrow_forwardFind the horizontal and vertical components of the 100=m displacement of a superhero who files from the top of a tall building following the path shown in Figure P3.52.arrow_forwardA football quarterback is moving straight backwards at a speed of 2.9m/s when he throws a pass to a player 22 m straight downfield.

- New York Rangers defenseman Daniel Girardi stands at the goal and passes a hockey puck 20 m and 45° from straight down the ice to left wing Chris Kreider waiting at the blue line. Kreider waits for Girardi to reach the blue line and passes the puck directly across the ice to him 10 m away. What is the final displacement of the puck? See the following figure.arrow_forwardA horizontal rifle is fired at a bull's-eye. The muzzle speed of the bullet is 700 m/s. The gun is pointed directly at the center of the bull's-eye, but the bullet strikes the target 0.021 m below the center. What is the horizontal distance between the end of the rifle and the bull's-eye?arrow_forwardYou buy a plastic dart gun, and being a clever physics student you decide to do a quick calculation to find its maximum horizontal range. You shoot the gun straight up, and it takes 5.0s for the dart to land back at the barrel. What is the maximum horizontal range of your gun? Express answer using two significant figures.arrow_forward
