- loaded 305 kgkg toboggan is traveling on smooth horizontal snow at 4.60 m/sm/s when it suddenly comes to a rough region. The region is 7.90 mm long and reduces the toboggan's speed by 1.50 m/sm/s. Part A: What average friction force did the rough region exert on the toboggan? Part B: By what percent did the rough region reduce the toboggan's kinetic energy? Part C: By what percent did the rough region reduce the toboggan's speed?1. A bullet of mass m, = 0.0500 kg is fired into a block of wood of mass m₂ = 0.850 kg. This block of wood is hanging from light wires. The bullet embeds in the block and the bullet and block combined swing up to a height of h=0.350 m. What was the speed of the bullet (vu) right before it hit the block of wood (ignore friction)? a. 4.64 x 10³ m/s b. 2.62 m/s c. 44.5 m/s d. 47.1 m/s e. 123 m/sA 309 g glass rolls down an incline and onto a horizontal platform where it hits a beverage can that is laying at rest on its side. The top of the incline is 11.0 cm above the horizontal platform. The beverage can is initially at rest and weighs 7.35 N. Which of following is the final velocity of the glass? Select one: a. 0.612 m / s b. −5.83 m / s c. −1.35 m / s d. −0.612 m / s
- A man that weights 93kg sits on a 210 kg boat. After deciding he wants to stay at his current location with his boat motionless, he throws an anchor that weights 32 kg horizontally with the speed of 4.4m/s. Assume there is no resistance from the water. What is the velocity of the boat with man after the anchor was thrown? draw a picture round significant figures show workA boy slips off a spherical ice mound of radius 7.

Assume the ice is frictionless.Alex Morgan, one of America's best forwards, kicks a 450. g soccer ball that was moving towards her at a speed of 12.0m/s, the impact caused the ball to leave her foot with a velocity of 20.0 m/s in the opposite direction. a. If the impact lasted for 0.250s, what force (magnitude and direction) did Alex exert on the soccer ball? b. What is one thing that she could do to make the soccer ball have a larger change in momentum?
- 9. A 1200 kg car drives at an initial velocity vo = 45 m/s along a highway. At t = 0, the driver releases the gas, and the car slows to a stop due to a drag force given by Fdrag = -b v, where b = 15 kg/s³. Derive a function for the car's velocity as a function of time and solve it for the car's velocity at 10, 20, and 30 s.A 1.50-mm-long, 500 gg rope pulls a 10.0 kgkg block of ice across a horizontal, frictionless surface.
