Mary slides down a snow-covered hill on a large piece of cardboard and then slides across a frozen pond at a constant velocity of +2.5 m/s. After Mary has reached the bottom of the hill and is sliding across the ice, Sue runs after her at a velocity of +4.4 m/s and hops on the cardboard. How fast (in m/s) do the two of them slide across the ice together on the cardboard? Mary's mass is 68 kg and Sue's is 58 kg. Ignore the mass of the cardboard and any friction between the cardboard and the snow and/or ice. (Indicate the direction with the sign of your answer.) m/s

A 238U nucleus is moving in the x direction at 5.0×105 m/s when it decays into an alpha particle (4He) and a 234Th nucleus. If the alpha particle moves off at 22 degrees above the x axis with a speed of 1.1×107 m/s, a) What is the speed of the thorium nucleus and b) What is the direction of the motion of the thorium nucleus ( degrees clockwise from the x axis)?
At an airport, Anna is stationary, Bert is walking at a speed of 1.0 m/s, Carla is standing while Dodong is walking on a platform that moves with a speed of 2.0 m/s. Anna observes Bert, Carla, and Dodong moving away from her in the same direction. Anna observes Dodong moving away from her at a speed of 3.0 m/s. What is Anna’s velocity relative to the ground or earth?
Sofia is playing a game with her friend, Kara, where she throwsM&M candies at Kara and Kara catches the M&M’s in hermouth. They begin standing 1.75 meters apart from eachother. Sofia throws the M&M at an angle of 60 degrees abovethe horizontal with a speed of 4.13 m/s. Kara’s mouth is145 cm above the ground when she catches the M&M. Whatheight above the ground did the M&M leave Sofia’s hand?Hint: Remember, even though the motion in the horizontaldirection is independent of the motion in the vertical direc-tion, they share the same time.
Anna Shcherbakova is a 2022 Beijing Olympics figure skating gold medalist for ladies’ singles.After warming up she starts her practice by skating towards the middle of the ice rink, 14 metersfrom the entrance. However, this time, one of her friends decided to trick her by pushing hertowards the middle at a velocity of 1.2 m/s (disregard friction between the ice and her skates).Recovering from the shock 2 seconds after, she starts pushing herself forward at an accelerationof 0.5 m/s2. What velocity will she have when she reaches the middle of the rink?

(a) Find the momentum of a asteroid heading towards Earth at 30.0 km/s. (b) Find the ratio of this momentum to the classical momentum. (Hint: Use the approximation that at low velocities.)
A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.70 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.35 m high, and from there it will fall into a pool (Fig. P3.42). (a) Will the space behind the waterfall be wide enough for a pedestrian walkway? (b) To sell her plan to the city council, the architect wants to build a model to standard scale, which is one-twelfth actual size. How fast should the water flow in the channel in the model?

In the 1968 Olympics in Mexico City, Bob Beamon shattered the record for the long jump with a jump of 8.90 m. His speed on takeoff was 9.5 m/s. How close did this athlete come to the maximum possible range in the absence of air resistance? (g in Mexico City is 9.78 m/s²)
1.b.In Example 2.12, two circus performers rehearse a trick in which a ball and a dart collide. Horatio stands on a platform 7.8 m above the ground and drops a ball straight down. At the same moment, Amelia uses a spring-loaded device on the ground to launch a dart straight up toward the ball. The dart is launched at 16.0 m/s. Find the time and height of the collision by simultaneously solving the equations for the ball and the dart. (Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.)
When the moving sidewalk at the airport is broken, as it often seems to be, it takes you 50 s to walk from your gate to baggage claim. When it is working and you stand on the moving sidewalk the entire way, without walking, it takes 75 s to travel the same distance. How long will it take you to travel from the gate to baggage claim if you walk while riding on the moving sidewalk?
