Q. The flywheel has mass 370 with a radius of 0.50 and can rotate up to 530. Assuming all of this stored kinetic energy could be transferred to the linear velocity of the 3200- car, find out the maximum attainable speed of the car.
Q. Two objects attract each other gravitationally with a force of 2.5×10-10 while they are 0.60 apart. Their total mass is 5.0. Find out their individual masses.
A coffee filter of mass 1.2 grams dropped from a height of 3 m reaches the ground with a speed of 0.7 m/s. How much kinetic energy Kair did air molecules gain from the falling coffee filter.
Two identical metallic blocks are connected by a light spring having the spring constant 100 N/m and an unstretched length of .30 m. A total charge Q is slowly placed on the system, causing the spring to stretch to an equilibrium length of .40 m. ..
A 3.2 mass attached to a spring with a spring constant of 114 is oscillating in a vat of oil, which damps the oscillations. If the damping constant of the oil is 10kg/s, how long would it take the amplitude of the oscillations to decrease to 1.0% ..
A 9.40kg projectile is fired vertically upward. Air drag decreases the mechanical energy of the projectile-Earth system by 69.5kJ throughout the projectile's ascent. How much higher would the projectile have gone were air drag negligible.
A 3.00 kg mass resting on a level table top is pulled along by a horizontal force of 16 N and accelerates at 4.00 meters per second per second. What is the force of friction between block and table.
Two parallel rods are each 0.50 m in length. They are attached at their centers to either end of the spring (spring constant = 150 N/m) that is initially neither stretched nor compressed.
What is an angular acceleration
A damped mass-spring system oscillates at 265 -Hz. The time constant of the system is 2.0 s. At t = 0, the amplitude of oscillation is 6.1 cm and the energy of the oscillating system is then 61.00 J.
How much time is necessary for the torso to come to rest
What additional experiment can help you decide between these two possibilities.
A small block of mass m = 1.5 kg slides, without friction, along the loop-the-loop track shown. the block starts from the point P a distance h = 54 m above the bottom of the loop of radius R = 17.0 m. What is the kinetic energy of the mass at the ..
