A 500- kg ice boat moves on runners on essentially frictionless ice. A steady wind blows, applying a constant force to the sail. At the end of an 10- s run, the acceleration is 0.5 m/s2.What was the acceleration at the beginning of the run?
What was the force due to the wind?
What retarding force must be applied at the end of 3 s to bring the ice boat to rest by the end of the next 3 s? (The wind is still blowing. Assume the boat was at rest at time t = 0.)
A paperweight, when weighed in air, has a weight of W = 7.4N. When completely immersed in water, though, it has a weight of Win water = 4.40 N. Find the volume of the paperweight.
What are the forces acting on the board due to the two supports as a diver of mass 63 kg stands at the end of the board over the water.
Winds pick up suddently,increasing the wave's amplitude to 6m. Explain how does this change in amplitude affect the wave's frequency and the amount of energy it transports?
A helicopter is ascending vertically with a speed of 5.98. At a height of 149 above the Earth, a package is dropped from a window. How long till the package hits ground.
The ball leaves his racket with a speed of 16.0 m/s at an angle 5.5 degrees above the horizontal. The horizontal distance to the net is 7.0 m and the net is 1.0 m high. Explain by how much did the ball clear the net?
A racing car travels with a constant tangential speed of 75 m/s around a circular track with a radius 625 m. Find (a) the magnitude of the car's total acceleration and (b) the direction of its total acceleration relative to the radial direction.
A doubly charged helium atom whose mass is 6.6 10 to 27 kg is accelerated by a voltage of 2200 V. What will be its radius of curvature if it moves in the plane perpendicular to a uniform 0.308 T field?
A curve with a 140 radius on a level road is banked at the correct angle for a speed of 20 . If an automobile rounds this curve at 30 , what is the minimum coefficient of static friction between tires and road needed to prevent skidding.
A double speed trap is set up on a freeway. One police cruiser is hidden behind a billboard, and another is some distance away under a bridge. As a sedan passes by the first cruiser, its speed is measured to be 99.7 mph.
After the Sun exhausts its nuclear fuel, its ultimate fate might be to collapse to a white dwarf state. In this state, it would have about the same mass as it has now, but its radius would be equal to the radius of the Earth.
How far did you travel on this trip? What was your average speed.
A rectangular loop with sides of lengtha=1.10cm andb=4.10cm is placed near a wire that carries a currenti(t)=3.14 + 1.04t2, where the current is in amperes and time is in seconds. The distance from the straight wire to the closest side of the loop..
