a cheetah moving with constant acceleration covers the distance between two points 105.0 m apart in 4.7 s. its speed as it passes the second point is 35.5 m/s what are its speed at the first point?
when 2.7 kg of salt solution is poured into a cylindrical bottle, 200mm in diameter, the liquid level rise by 75mm. calculate the density and specific gravity
a particle falling under gravity is subject to a retarding force proportional to its velocity.find its position of time , if its starts from rest , and show that it will eventually reach a terminal velocity
Find the diameter of an 18 m (L) long steel wire that will stretch no more than 9 mm(∆L) when a load (stress) of 3800 N is hung on the end of the wire. The Young’s Modulus for steel wire is 200 x 109 N/m2
Juan pulls the sled with a force of 255 N moving
horizontally 10.00 m.what is the work done by Juan on the sled
A vertical angle of -12°25' is measured to the top of a water tank from an instrument set up on a hill 585.0m away from it. The telescope of the instrument is 1.45m above the ground whose elevation is 462.73m. considering the effects of earth's curvature and refraction, determine the elevation of the base of the water tank if the tank is 32.0m high.
