- 9- Solve b-) with explainEmma and Katie are racing along in their new wagon. Upon reaching the bottom of the hill traveling at 13.2 m/s, Katie notices her teddy bear 12.0 m in front of them, panics and locks the brakes sending the wagon into a skid. If the wagon and its contents have a total mass of 1.50 x10^1 kg, and the coefficient of kinetic friction between the road and the rubber wagon tires is (0.75), by how much does the wagon miss the bear?Vmax In a laboratory experiment, a sphere of diameter 8.0 mm is released from rest at t = 0 at the surface of honey in a jar, and the sphere's downward speed v when it travels in the honey is found to be given by v = Vmax (1 - e-t/T), where 0.040 m/s and T = 0.50 s. (a) Obtain an expression for a(t). (b) Draw graphs for v(t) and a(t) for the time interval 0 to 2.0 s. (c) Obtain an expression for x(t), choosing the positive x axis as downward, and draw the graph for this func- tion. (d) Use your x(t) graph to determine the time interval needed for the sphere to reach the bottom of the container if the surface of the honey is 0.10 m above the bottom of the jar. ... =
- a baseball player sprints to the back of the outfield to catch a fly ball. they successfully catch the ball, but don’t have enough time to slow themselves before crashing into the wall. how do the padded walls in the outfield keep players safe.You find yourself stranded on the middle of a frozen pond. The surface is so slick you are unable to get any traction. In an effort to save yourself, you take off your boot and throw it toward the west. This results in... A. you staying put. B. you sliding off to the east slower than the boot's speed. C. you sliding off to the east faster than the boot's speed. D. you sliding off to the west faster than the boot's speed. E. you sliding off to the west slower than the boot's speed.A hockey puck (mass = 2 kg) leaves the players stick with a speed of 20 m/s and slides on the ice before coming to rest.The coefficient of friction between the puck and the ice is 0.9.

- Lionel Messi scores a last second goal and, in celebration, runs as fast as he can, drops to his knees and slides along the wet grass of the field. Messi has been clocked (this is true) at a top speed of 9 meters per second in a game. Let's take this as his maximum velocity and the speed he is moving right before he drops down to slide.Take Messi's mass to be 72 kilograms, and take the coefficient of kinetic friction between skin and wet grass to be 0.4How far does Messi slide?1. Ember is sailing a fibre glass fishing boat of mass 1600 pounds and enters a marina at 2.58 m/s [W 25.0° N]. Over a time interval of 4.00 s Ember turned the boat towards a slip and slowed to 1.15 m/s [W 25.0° S]. i. What was the average acceleration of the boat during the parking sequence? Criteria: ii. If the boat hits a deck boat of mass 3000 pounds while parking, how much force will the fishing boat experience? Criteria:In the movie The Rocketeer, a teenager discovers a jet-powered backpack in an old barn. The backpack allows him to fly at incredible speeds. In one scene, however, he uses the backpack to rapidly accelerate an old pickup truck that is being chased by “bad guys.” He does this by bracing his arms against the cab of the pickup and firing the backpack, giving the truck the acceleration of a drag racer. Is the physics of this scene “Good,”“Bad,” or “Ugly?” Draw and Explain.
