You are driving in one direction on a long straight road. You drive in the positive direction at 126 km/h for 30.0 minutes, at which time you see a police car with someone pulled over, presumably for speeding. You then drive in the same direction at 100 km/h for 45.0 minutes.
(a) How far did you drive?
(b) What was your average velocity in kilometers per hour? (a) answer in km (b) answer in km/h
If a car of mass 1000 kg is moving along a highway at 92 km/h, what is car's kinetic energy as determined by someone standing alongside the highway.
A series RLC circuit consists of a 96.0 ? resistor, a 7.00 mHinductor, and a 1.40 nF capacitor. What is the power supplied to the circuit if ? =1/2?0
A space vehicle is orbiting Earth in the circular orbit with a radius of 10,300,000 m. What is the minimum increase in speed that is essential for the vehicle to escape Earth's gravitational field? The mass of Earth is 5.97 x 10^24 kg and G = 6.67 X ..
After falling from rest from a height of 35 m, a 0.45 kg ball rebounds upward, reaching a height of 25 m. If the contact between ball and ground lasted 1.8 ms, illustrate what average force was exerted on the ball?
Three masses are placed at different points along a meter stick of negligible mass: 0.09 kg at 0.98 m, 0.04 kg at 0.55 m, Where's the center of mass of the system
A series RCL circuit contains a 4.99-µF capacitor and a generator whose voltage is 11.6 V. At a resonant frequency of 1.20 kHz the power delivered to the circuit is 24.1 W. Find the value of the inductance
If a person were to push hardly on a solid wall will the work be done? Also, why would it be exhausting to push hardly against this solid wall?
A turtle crawls along a straight line, which we will call the x-axis with the positive direction to the right. The equation for the turtle's position as a function of time is x(t) = 50.0 cm +(2.00 cm/s)t -(.0625 cm/s^2)t^2 At what time is the turt..
You are trying to overhear a juicy conversation, but from your distance of 15m. It sounds like only an average whisper of 20 dB. So you decide to move closer to give the conversation a sound level of 60 dB instead. How close must you come.
