Q1. The best leaper in the animal kingdom is the puma, which can jump to a height of 12.4 ft when leaving the ground at an angle of 43°. With what speed, in SI units, should the animal leave ground to reach that height?
Q2. A disk of radius has a total charge uniformly distributed over its surface. The disk has negligible thickness and lies in the xy plane. What is the electric potential V (z) on z axis as a function of z, for z>0?
Express how unmet basic physiological needs of oxygen, nutrition, temperature, and humidity threaten clients' safety.
A beam of 6 MeV electrons passes through a 400 micro-meter thick silicon detector. Estimate the energy lost by the electrons when crossing 200 micro-meters, 300 micro-meters and the full thickness of the detector.
A pump, submerged at the bottom of a well that is 34 m deep, is used to pump water uphill to the house that is 50 m above the top of the well, as shown above. All pressures are gauge pressures. Avoid the effects of friction, turbulence, and viscosity..
Under the influence of its drive force, a snowmobile is moving at a constant velocity along a horizontal patch of snow. When the drive force is shut off, the snowmobile coasts to a halt.
Light from a He-Ne laser (= 632.8) strikes a pair of slits at normal incidence, forming a double-slit interference pattern on a screen located 1.10 from the slits. The figure shows the interference pattern observed on the screen.
A 67.3 kg sled starts at rest on a horizontal road. The coefficient of kinetic friction between the sled and the road is μk = 0.202. A man pulls the sled a distance 5.07 m along the ground by exerting a constant force of magnitude 532 N on a rope tha..
If the surface of the water is calm and the pool is h = 1.52 m deep, find out the minimum diameter of the raft that would prevent the diamond from being seen.
How fast can this car round a second curve of radius 320m?
A 23.00 kg chair initially at rest on a horizontal floor requires a 364N horizontal force to set it in motion. Once the chair is in motion, a 328N horizontal force keeps it moving at a constant velocity. A 23.00 kg chair initially at rest on a horizo..
W hat is the downward acceleration of the blue spool
An elevator cable can withstand a maximum tension of 19,500N before breaking. The elevator has a mass of 480 kg and a maximum acceleration of 2.24 m/s2. Engineering safety standards require that the cable tension never exceed two-thirds of the breaki..
A 0.525 kg ball starts from rest and rolls down the hill with uniform acceleration, travelling 150 m throughout the second 10.0 rm s of its motion.
