Q. Two crewmen pull a boat through a lock, as shown in the figure below. One crewman pulls with a force of size F1 = 130N at an angle of = 34° relative to the forward direction of the boat. The second crewman, on the opposite side of the lock, pulls at an angle of 45°. How large a force F2 must the second crewman pull so that the net force of the two crewmen is in the forward direction?
In a 100 m race, Maggie and Judy cross finish line in a dead heat, both taking 11.4s. Accelerating uniformly, Maggie took 1.80 s and Judy 2.90s to attain maximum speed, which they maintained for the rest of the race. What was Maggie's acceleration..
Note down that since each oscillator is attached to two "springs", and each "spring" is half the length of the interatomic bond, the effective interatomic spring stiffness for one of these oscillators is times estimated value given above.
An infinitely long line of charge has linear charge density 5.00 x10-12 C/m. A proton (mass 1.67 x10-27 kg, charge +1.60 x10-19 C) is 18 cm from the line and moving directly toward the line at 1.50 x103 m/s. How close does the proton get to the li..

An electron and a proton each have a thermal kinetic energy of 3×kBT/2. Compute the de Broglie wavelength of each particle at the temperature of 2050 K. (kb is Boltzmann's constant, 1.38×10-23 J/K).
An electric scooter has a battery capable of supplying 140 Wh of energy. If friction forces and other losses account for 60 percent of the energy usage, what altitude change can a rider achieve while driving in hilly terrain, if the rider and scooter..
There are 2 inclines A & B. Identical carts are placed on the top of each incline and release them from rest. Both inclines have the similar height and are friction less, but angles of the two incline are not the similar. Would carts acceleration ..
