A bicycle has wheels with a diameter of 0.600 m. It accelerates uniformly and the rate of rotation of its wheels increases from 175 rpm to 275 rpm in a time of 19.3 s. Find the linear acceleration of the bicycle.
A proton travels with a speed of 8.34×105 m/s at an angle of 32.3° with the direction of a magnetic field. The field exerts a force of 3.00×10-17 N on the proton. What is the strength of the field?
An airplane needs to reach a velocity of 203.0 km/h to take off. On a 2000 m runway, what is the minimum acceleration necessary for the plane to take flight?
The spring scale in the diagram below reads 10.5 N. If the cart moves toward the right with an acceleration also towards the right of 3.25 m/s2, what is the mass of the cart?
Determine the maximum wavelength of the photon that hydrogen in the excited state ni = 6 can absorb. The energy of the ground state of hydrogen is -13.6 eV.
Two point charges, separated by 1.5 cm have charge values of 2.0 micro C and -4.0 micro C respectively. What is the value of the electrostatic force between them?
A cart (with wheels) sits on a horizontal table. The front of the cart is a vertical wall, with mass M = 0.908 kg held against the wall. You want to push the cart forward with an acceleration of magnitude a so the mass M can be released and it wil
A 2.5 kg block of ice at a temperature of 0C and an initial speed of 5.7 m/s slides across a level floor. If 3.3*10^5 J are required to melt 1.0 kg of ice, how much ice melts, assuming that the initial kinetic energy of the ice block if entirely c
