A Toyota Prius driving north at 61.0 {\rm mph} and a VW Passat driving south at 41.0 {\rm mph} are on the same road heading toward each other (but in different lanes). (We take the positive direction to be north.) What is the velocity of Toyota Prius relative to the VW Passat when they are 250...

What mass (in grams) of steam at 100 C must be mixed with 166 g of ice at its melting point, in a thermally insulated container, to produce liquid water at 31.0 C? The specific heat of water is 4186 J/kg K. The latent heat of fusion is 333 kJ/kg, and the latent heat of vaporization is 2256 kJ/kg.

You drive a car 600 {\rm ft} to the east, then 390 {\rm ft} to the north. What is the magnitude of your displacement?

Two crates, of mass m1 = 45 kg and m2 = 110 kg, are in contact and at rest on a horizontal surface (Fig. 4-54). A 620 N force is exerted on the 45 kg crate. The coefficient of kinetic friction is 0.15. (a) Calculate the acceleration of the system.(b) Calculate the force that each crate exerts...

What net force would actually be necessary to stop an automobile of mass 890 traveling initially at a speed of 52.0 in a distance equal to the diameter of a dime, which is 1.8 ?

Hello,I attached my problem sheet. I need the answer for questions 003,004,005,006. thank you.

A particlemoves in the xy plane with constant acceleration. At time zero, the particle is at x = 8.5 m, y = 3.5 m, and has velocity v = (5 m/s) i + ( 4.5 m/s) j . The acceleration is given by a = (1 m/s2) i + (6.5 m/s2) j . a) What is the x component of velocity after 1.5 s? Answer in...

A sailboat is heading directly north at a speed of 20 knots (1 knot = 0.514 m/s). The wind is blowing towards the east with a speed of 17 knots. (a) Determine the magnitude and direction of the wind velocity as measured on the boat in knots (b)What is the component of the wind velocity in the...

your driving down the highway late one night at 19 m/s when a deer steps onto the road 43 meter in front of you. your reaction time before stopping on the breaks is .50 s and the maximum deceleration of your car is 12 m/s. How much distance is between you and the deer when you come to a stop?

What does the speed of the airplane depend on?
