- You are playing a game and you push a cart to give it in. speed. The cart starts at the bottom (zero) of a ramp and after reaching the top of the ramp, the cart travels across a horizontal track w/ friction. The mass of the cart is 44 x 10^-3 kg. The ramp is 56 cm high. The length is 70 cm. What can you infer of the intial speed in (m/s)On an essentially frictionless, horizontal ice rink, a skater moving at 4.0 m/s encounters a rough patch that reduces her speed by 44% due to a friction force that is 28% of her weight.A car of mass 1670kg initially at a speed of 80 km/m crushes into a wall, if the accident lasted for 0.2 sec. what is the amount of force exerted in the car during the crash
- A hockey puck with mass 0.163 kg is pushed across the ice with a constant force of 0.37 N. The coefficient of kinetic friction between the puck and the ice is 0.13. After a distance of 1.3 m, what is the puck's speed in m/s?A worker pushes a 35.0-kg package on a horizontal roller-belt conveyor until it reaches a certain speed. The package then coasts on the horizontal conveyor, all the while slowing down, until it comes to a complete stop after moving 1.20 m. While the package is coasting on the conveyor, the opposing friction force averages 6.00 N. Use the WET to find the speed of the package after the worker pushes it and just as it begins to coast. 0.625 m/s 0.759 m/s 0.600 m/s 0.510 m/s 0.802 m/s 0.641 m/sWhile walking on water, an arctic wind freezes the water beneath your feet and you now find yourself stuck in the middle of a 15m diameter lake on top of a frictionless layer of ice. Unable to just walk off, you decide to push off your physics book with a force of 80.0N for 0.1s. How long in minutes will it take you to reach the shore if your mass is 75kg?
- A car of mass 1650 kg, initially at a speed of 70km/h, crushes into a wall, if the accident lasted for 0.2 sec, what is the amount of force exerted in the car during the crash?The froghopper holds the title of the best jumper of the animal world. A 0.0198-gram (1.98 X 10-5 kg) froghopper can accelerate from 0m/s to 4m/s in only one one thousandth of a second (0.001 s) as it jumps. What is the force delivered to the froghopper as it makes this jump?
