A projectile is fired with an initial speed of 36.7m/sat an angle of 42.1 above the horizontal on a long flat firing range.
1. Decide the total time in the air.
2. Decide the speed of the projectile 1.30s after firing.
3. Determine the maximum height reached by the projectile.
4. Determine the total horizontal distance covered (that is, the range).
a coal-fired electric power plant has an overall efficiency of 28 and an output of 1845 megawatts. how many tera joules
An RLC series circuit is connected to a 120-Vrms, 60Hz line. The inductance is 0.05 H, the average current is 11A and the current leads the voltage by 45 degrees.
The brakes are applied to a car traveling on a dry, level highway. A typical value for the magnitude of the car's acceleration is 5.45 m/s2. If the car's initial speed is 33 m/s, how long does it takes to stop and how far does it travel, starting ..
