The car's final velocity is 11.6 m/s in the opposite direction.
Answer:
It is given that power = 5000 W for 120 V and resistance is per 1000 ft of wire. The wire is 750 ft away from 120 V source. We need find the voltage delivered to this load.
Resistance of 750 ft wire, =
Using Ohm's Law:
Voltage delivered to the load,
Answer:
acceleration: 5.48 m/s²
time taken: 9.3 seconds
Given:
- mass: 1200 kg
- force: 6572 N
- initial velocity: 15 m/s
- final velocity: 66 m/s
