Suppose that the coefficient of kinetic friction between Zak's feet and the floor, while wearing socks, is 0.250. Knowing this, Zak decides to get a running start and then slide across the floor.   If Zak's speed is 3.00 m/sm/s when he starts to slide, what distance ddd will he slide before stopping? Use 9.81 m/s2m/s2 for the acceleration due to gravity.

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

A hot air balloon begins to rise from rest. The lift on the balloon due to the buoyant force is 5000 N. In order to minimize the time until the passenger is reunited with their cell phone, what should the horizontal component of the passenger’s velocity be so that they land directly on their phone which is initially 3 m away in the horizontal direction?

A robot pushes a 20-kg giftbox on the horizontal surface as part of the moving job for the holiday season, the force is 27 N to the right as shown. The box does not move. The coefficients of friction between the floor and box are μs = 0.75 and μk = 0.40. What is the magnitude (absolute value) of the friction force on the box, in Newtons? Use g = 10 m/s2.

You place a crate of mass 47.7 kg on a frictionless 3.61-meter-long incline. You release the crate from rest, and it begins to slide down, eventually reaching the bottom 1.15 s after you released it. What is the angle of the incline? 1 50.7 degrees 76.1 degrees 3. 42.3 degrees 4 33.8 degrees

A car of mass 822 kg is traveling 26.4 m/a when the driver applies the brakes, which lock the wheels. The car skids for 4.47 s in the positive x direction before coming to rest. What is the cars acceleration in m/ s2? what magnitude force in N acted on the car during this time? How far in m did the car travel?

Blocks 1 and 2 are moving to the right on a frictionless surface by the tension TB = 36 N as shown. m1 = 2.0 kg, and m2 = 3.2 kg. What is the magnitude of the acceleration of block 2, in m/s²? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. m₁ TA m₂ TB

A woman pulls a cloth out from under a 200 g bowl sitting on a table. The bowl is 30.0 cm from the far edge of the cloth, and the cloth exerts a friction force of 0.125 N on the bowl. Assume the cloth is pulled with a constant horizontal acceleration of 2.80 m/s2. What distance (in m) does the bowl travel relative to the top of the table? (Assume the cloth moves in the +x-direction and notice that it moves more than 30.0 cm relative to the top of the table.)

While two forces act on it, a particle is to move at the constant velocity = (3.58 m/s) -(-3.26 m/s). One of the forces is F1 = (1.88 N) + (-5.85 N). What is the other force? Number i + i j Units

The figure shows three blocks attached by cords that loop over frictionless pulleys. Block B lies on a frictionless table; the masses are mA blocks are released, what is the tension in the cord at the right? 6.70 kg, mB 6.20 kg, and mc = 12.0 kg. When the B C Number Units
