Suppose that each vehicle is initially moving at 9.60 m/s and that they undergo a perfectly inelastic head-on collision. Each driver has mass 80.0 kg. Including the masses of the drivers, the total masses of the vehicles are 800 kg for the car and 4000 kg for the truck. If the collision time is 0.140 s, what force does the seat belt exert on each driver?
You want to store 10^-5 C of charge on a capacitor, but you only have a 100 V voltage source with which to charge it. What must be the value of the capacitance
An athlete has a large lung capacity, 7.0 L. Assuming air to be an ideal gas, how many molecules of air are in the athlete's lungs
A factory worker pushes horizontally to the right on a 250 N crate with a force of P = 75.0 N on a horizontal rough floor. A 135 N crate rests on top of the one being pushed and moves along with it. Call the bottom crate {rm A} and the top crate {..
When scuba diving, you must equalize the pressure inside your body with the water outside every few meters you dive downward or swim upwards in order to avoid serious health complications. Calculate how far underwater you must dive
A beam of electrons traveling with speed 0.8 x10^(8) m/s passes through a slit of width 10^(-5) m. Because of the uncertainty in the lateral position of the beam, there will be an uncertainty in the transverse momentum as well.
A disk has radius R = 1.20 cm. Its surface charge density is 1.70 x 10-6 C/m2 from r = 0 to r = R/2 and 9.10 x 10-7 C/m2 from r = R/2 to r = R, What is the total charge (in C) on the disk
A gas is to be expanded from initial state i to final state f along either path 1 or path 2 on a p-V diagram. What is the change in the internal energy of the gas along path 2
Two charged plates create a potential difference of 190 V. At a point halfway between the plates an electron is released from rest. What was the initial speed and direction of the proton
You want to design the loop-the-loop toy. The idea is that a ball of mass m=0.01 kg, determine the minimum height necessary for the ball to remain in contact with the track during the whole loop-the-loop journey
Two gliders are positioned on an air track, M1 and M2. M2 is stationary and M1 is then pushed down the track and collides with M2. They stick together and continue down the track.
How far does the car go before it stops. An advertisement claims that a sportscar can accelerate from rest to 100 km/hr in 7.70 s.
An apple drops from the tree and falls freely. The apple is originally at rest a height {H0} above the top of the grass of a thick lawn, which is made of blades of grass of height {h}. When apple enters the grass, it slows down at a constant rate ..
