An engineer in a locomotive sees a car stuck on the track at a railroad crossing.An engineer in a locomotive sees a car stuck on the track at a railroad crossing in front of the train. When the engineer first sees the car, the locomotive is 130 m from the crossing and its speed is 17 m/s.
If the engineer's reaction time is 0.36 s, what should be the magnitude of the minimum deceleration to avoid an accident?Answer in units of m/s^2
A charge of -6 nC is at the origin and a second charge of 11.0 nC is at x = 5.0m. Find the magnitude and direction of an electric field halfway in between the two charges.
Two boats start together and race across a 62-km-wide lake and back. Boat A goes across at 62 km/h and returns at 62 km/h. Boat B goes across at 31 km/h, and its crew, realizing how far behind it is getting, returns at 93 km/h.
Computing the kinetic energy, takeoff speed, and kinetic energy per kilogram.
A .450 kg ice puck, moving east with a speed of 3m/s, has a head-n collision with a .900 kg puck initially at rest. Assume a completely elastic collision, what will be the speed and direction of each object after collision.
An astronaut weighs 7*10^2 N on the surface of the earth (M earth=5.98*10^24 kg). What is her weight 7.70*10^6 m above the earth.
While a woman stands with two feet on a scale, the scale reads 490 N. When she lifts one foot, scale reads more or less.
A typical red blood cell subtends an angle of only 1.91E-5 rad while viewed at a person's near-point distance of 25cm. Assume a red blood cell is examined with a compound microscope in which the objective and eyepiece are separated by a distance o..
A 70 kg bicyclist rides his 7.8 kg bicycle with a speed of 16 m/s. How much work must be done by the brakes to bring the bike and rider to a stop.
A 2 g lead (cp = 128 J/kg•°C) bullet travelling at 325m/s is stopped by the large tree. If half the kinetic energy of the bullet is transformed into internal energy and remains with the bullet whereas the other half is transmitted to the tree, wha..
A motorist drives south at 22 m/s for 3.00 min, then turns west and travels at 25.0 m/s for 2.40 min, and finally travels northwest at 30 m/s for 1.00 min. For this 6.40 min trip, find out the following values.
guess the force between a proton and an electron at the Bohr radius of 0.5Å (1 Å=10-10 m). The magnitude of the charge of an electron, as well as a proton, is 1.6·10-19 C.
A straight, stiff wire of length 1.00 m and mass 21g is suspended in a magnetic field B = 0.58T. The wire is connected to an emf. How much current must flow in the wire and in what direction so that the wire is suspended and the tension in the sup..
