You find yourself trapped in the middle of a large frozen lake. Assume the ice has no friction. All you have on your is warm winter clothing and no way to call/signal for help. You can just barely see the shore in the distance. Use your physics knowledge of Newton's laws to help get you off the lake. Explain your reasoning.

A 1090 kg boat is traveling at 92 km/h when its engine is shut off. The magnitude of the frictional force ?→?f→k between boat and water is proportional to the speed v of the boat: fk = 85v, where v is in meters per second and fk is in newtons. Find the time required for the boat to slow to 46 km/h.

Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.

A 781 N sprinter can push his feet back against the starting blocks with a force of 1852 N in the horizontal direction.  If the force is generated for 0.28 s, determine the horizontal velocity of the runner out of the blocks. Include magnitude and direction when reporting vectors.

Tom enlists the help of his friend John to move his car. They apply forces to the car. F1 = 430 N and F2 = 347 N and friction is negligible. Mass of car = 3500 kg O1= -25 degrees and O2 = 12 degrees (assume the car faces the positive x-axis before the forces are applied. A) Find the force (in N) exerted on the car     Magnitude =     Direction (counterclockwise from the +x-Axis) = ______________ degrees B) What is the acceleration (in m/s squared) of the car?     Magnitude =   __________ m/s squared     direction (counterclockwise from the +x-Axis) ______________ degrees

In the sport of parasailing, a person is attached to a rope being pulled by a boat while hanging from a parachute-like sail. A rider is towed at a constant speed by a rope that is at an angle of 15° from horizontal. The tension in the rope is 2300 N. The force of the sail on the rider is 30° from horizontal. What is the weight of the rider?

A commercial airplane is coming in for a landing. Just before it hits the runway it is moving at 76 m/s. The plane has a mass of 20,000 kg. The runway is 1.6km long and, obviously, the airplane needs to be stopped before it reaches the end of the runway. How large is the braking force the airplane needs to stop safely before the end of the runway?

A flea jumps by exerting a force of 1.02 x 10-5 N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 1.16 × 10-6 N on the flea. Find the direction and magnitude (in m/s²) of the acceleration of the flea if its mass is 6.0 × 107 kg. (Let us assume that F points to the right. We will consider this to be the +x direction and vertical to be the +y wind direction.) magnitude 17.1 Did you draw a free-body diagram, and identify the forces acting on the flea? Consider the forces acting on the flea during the time it is in contact with the ground. m/s² direction 6.49 Review vector components. In which of the four quadrants is the resultant force located?° (measured clockwise from the vertical) Tutorial Supporting Materials Physical Constants Submit Answer

A stubborn dog is being walked on a leash by its owner. At one point, the dog encounters an interesting scent at some spot on the ground and wants to explore it in detail, but the owner gets impatient and pulls on the leash with force F ⃗ = (98.0i ^ + 132.0j ^ + 32.0k ^ )N along the leash. (a) What is the magnitude of the pulling force? (b) What angle does the leash make with the vertical?

A toy boat is being pushed with a force of 40.0 N [W] by its engines in a pond. A strong wind blows from the north, which exerts a force of 30.0 N on the boat. What is the net force acting on the ferry?   Question 1 options: a 50.0 N [W 36.9° S] b 70.0 N [W 53.1° S] c 50.0 N [W 53.1° S] d 70.0 N [W 36.9° S]
