A football field is covered with frictionless ice. A 90.0 kg player is skating down the field with a constant velocity v= 4.01i + 3.0j m/s. A 400 g football is thrown towards the player with a straight, horizontal pass. The velocity of the football the moment before it reaches the player's hands is v= 20.0i + 15.0j m/s. The player catches the ball and the two slide along the ice with a final velocity vf. (a) Find the final velocity, of, of the player holding the ball. Write the velocity vector in component form (e.g., Á = Axi+ Ayj). Report your answer to two decimal places. (b) Find the change in kinetic energy of the player + football system. Round your answer to the nearest integer. Note: the x and y directions are in the horizontal plane, as shown below. The x-direction points along the length of the field and the y-direction points along the width of the field. The player and ball do not travel in the vertical direction. FOOTean neld

From what might be a possible scene in the comic book The X-Men, the Juggernaut (mJ) is charging into Colossus (mC) and the two collide. The initial speed of the Juggernaut is vJi and the initial speed of Colossus is vCi. After the collision, the final speed of the Juggernaut is vJf and the final speed of Colossus is vCf as they each bounce off of the other, heading in opposite directions. a. What is the impulse experienced by the Juggernaut? b. What is the impulse experienced by Colossus? c. In your own words, explain how these impulses must compare with each other and how they are related to the average force each superhero experiences during the collision.
A century-old platter falls vertically downward. Upon breaking, its fragments fly off parallel to the ground with velocity 1 = 2.4 m/s and V2 = 5.4 m/s. Find mass ml and mass m2 in kg Vi 25.0° V2 m1 m2 45.0°
Jonathan and Jane are sitting in a sleigh that is at rest on frictionless ice. Jonathan’s weight is 800 N, Jane’s weight is 600 N, and that of the sleigh is 1000 N. They see a poisonous spider on the floor of the sleigh and immediately jump off. Jonathan jumps to the left with a velocity of 5.00 m/s at 30.0° above the horizontal (relative to the ice), and Jane jumps to the right at 7.00 m/s at 36.9° above the horizontal (relative to the ice). Calculate the sleigh’s horizontal velocity (magnitude and direction) after they jump out.
V:00 a 46 For testing, a jetski coming in at 34.1 m/s collides with a tree and stops in around 1 second. A dummy passenger weighing 1481.3 N is protected by an airbagthat slows its velocity in 1.7 s. What is the magnitude of average force does the dummy experience during the collision? (N) Answer: 3028.86 The correct answer is: 3028.86
A baseball with mass of 0.16 kg is batted into the air. Its initial speed is 37.7 m/s, directed at an angle 30 degrees above the horizontal. After 0.10 seconds, what is the horizontal component of the ball's velocity (in m/s)?
A loaded gun is dropped on a frozen lake. The gun fires, with the bullet going horizontally in one direction and the qun sliding on the ice in the other direction. The bullet's mass is 0.04 kg, and its speed is 305 m/s. If the gun's mass is 2.1 kg, what is its speed (in m/s)? m/s
A 50-kg girl is standing on a 139-kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.64 m/s to the right relative to the plank. What is the velocity of the plank relative to the ice surface? Submit Answer Tries 0/10
Kyle, a 95.0 kg football player, leaps straight up into the air (with no horizontal velocity) to catch a pass. He catches the 0.430 kg ball precisely at the peak of his jump, when he is 0.437 meters off the ground. He hits the ground 0.0307 meters away from where he leapt. If the ball was moving horizontally when it was caught, how fast was the ball traveling? ball's speed: m/s
A0.3 kg ball on a rail is rolled down an incline, and then rolls across a table on a horizontal rail. It leaves the rail, and strikes the floor. Assume friction on the rail is negligible. A student finds that it takes 0.055 seconds to pass through a pair of photogates that are 0.183 m apart. The edge of the rail is 1.11 m above the floor. Find the horizontal velocity of the ball as it passes through the photogates. m/s How long does it take to hit the ground after leaving the rail? How far away from the edge of the table should a student place a coin so that the ball would hit the coin? m
A man holding a rock sits on a sled that is sliding across a frozen lake (negligible friction) with a speed of 0.530 m/s. The total mass of the sled, man, and rock is 93.0 kg. The mass of the rock is 0.320 kg and the man can throw it with a speed of 16.5 m/s. Both speeds are relative to the ground. Determine the speed of the sled (in m/s) if the man throws the rock forward (i.e., in the direction the sled is moving). m/s Determine the speed of the sled (in m/s) if the man throws the rock directly backward. m/s
