One of the asteroids, asty, looks like an elongated potato. Surprisingly it has a tiny (compared to asty) spherical moon! This moon called Dactyl has a mass of 4.20x1016kg, and a radius of 1.57x104 meters, according to Wikipedia. Your friend just said that on a planet that size, that a sneeze would give you escape speed. We are curious now. Find the escape speed on Dactyl.
A car with an initial speed of 10.7 m/s accelerates at a uniform rate of 0.92 m/s squared for 3.6 s. find the final speed and displacement of the car
A person with perfect pitch sits on the bus bench listening to the 442 Hz horn of an approaching car. If the person detects a frequency of 479 Hz, how fast is the car moving.
A 1040 kg car carrying four 80 kg people travels over a rough "washboard" dirt road with corrugations 2.0 m apart that causes the car to bounce on its spring suspension. The car bounces with maximum amplitude as its speed is 21 km/h. The car now stop..

A 2.0 m-long cylindrical steel wire with a cross-sectional diameter of 4.0 mm is placed over a light, frictionless pulley, with one end of the wire connected to a 5.0 kg object and the other end connected to a 3.0 kg object. By how much does the w..
An ac source of period T and maximum voltage V is connected to a single unknown ideal element that is either a resistor, an inductor, or a capacitor. At time t=0 the voltage is zero.
A spherical Van de Graaff ball of radius 0.15 m is charged to 500,000 Volts. It is spinning at 60 rpm; calculate the magnitude of its magnetic moment
A 36.0 g bullet moving at 478 m/s strikes a 3.7 kg bag of flour that is on ice, at rest. The bullet passes during the bag, leaving at 255 m/s. How fast is the bag moving when the bullet exits.
