A 52-kg pole vaulter running at 13 m/s vaults over the bar. Her speed when she is above the bar is 1.0 m/s. Neglect air resistance, as well as any energy absorbed by the pole, and determine her altitude as she crosses the bar.
Over a time interval of 1.92 years, the velocity of a planet orbiting a distant star reverses direction, changing from +19.7 km/s to -19.1 km/s.
A car is travelling with a velocity of + 88.0 km/h. It accelerates at a constant rate of 20 m/s2. If the acceleration lasts for 5.6s, what is the final velocity of the car.
Police determine skid marks 83 m long on the highway showing where the car made an emergency stop. Assume that the acceleration was -10 m/s2 (about the highest for dry pavement), how fast was the car going.
Assuming that all the heat generated by the resistor is absorbed by the solid substance, and that it takes 4 minutes to raise the temperature from 20to 80 degrees C, compute the specific heat for the substance.
A 50-kilogram woman balances on one heel of a pair of high heel shoes. If the heel is circular with radius of .5 cm, what pressure does she exert on the floor.
Assume that the balloon rises slowly so that the temperature inside is the same as outside. Illustrate what will happen if the balloon is made up of rigid material?
A charge of -2.6 × 10-9 C is at the origin and a charge of 8.1 × 10-9 C is on x-axis at x = 3 m. At what two locations on the x-axis (xpositive, xnegative) is the potential zero.
A spring oscillator is designed with a mass of 0.258 kg. It operates while immersed in a damping fluid, selected so that the oscillation amplitude will decrease to 1.00% of its initial value in 8.34 s
A supertanker with the mass of 4.67 × 10^8 kg is moving with a constant velocity. Its engines generate a forward thrust of 8.71 × 10^6 N.
An football is punted at 25.0 m/s at an angle of 30.0 degree above the horizon. What is the velocity vector of the ball when it is 5.00 m above the level ground
A line of charge with uniform density of 28.0 nC/m lies along the line y = -15.0 cm, between the points with coordinates x = 0 and x = 32.0 cm
