2. A car of mass 1000 kg is moving along a straight horizontal road. The engine of the car is working at a constant rate of 25 kW. When the speed of the car is vm s-', the resistance to motion has magnitude 10v newtons.(a)Show that, at the instant when v=20, the acceleration...
A 2000 kg car accelerates from rest to a velocity of 20 m/s in 10 seconds. What is the power of the engine during this acceleration? A car of mass 1000 kg accelerates uniformly from rest to a velocity of 54...
The engine of a car of mass 2000 kg has a normal rated power 80 kW. It experiences a constant resistive force which is of its weight when it is travelling on a straight road. Now, this car accelerates from rest at 2 m/s2 (A) The maximum duration of uniform acceleration will be...
A 2,500 kg car accelerates uniformly from 35.0 m/s to 78 m/s in 20.0 s. What is the net force exerted on the car? A car of mass 700 kg accelerates from rest to a speed of 45 m/s in 9.0 s. Determine the net force acting o...
1 A truck accelerates uniformly along a straight, horizontal road. The mass of the truck is2.0*10^4kg .(a) The speed of the truck increases from rest to 12 m/s in 30s.Calculate(i) the distance travelled by the truck during this time,distance =[2](ii) the resultant force on the tr...
The ozone mass transfer is influenced by many factors, which can be divided into hydrodynamic and physicochemical effects. Ozone itself is unstable and can quickly decompose into molecular oxygen leading to a low utilization rate [8]. Further, ozone alone does not cause complete oxidation of some...
Before docking, the center of mass of the protein was used as the center of the box (see Table 1 for the center coordinates of the protein), and the appropriate X, Y, and Z edge lengths were adjusted to construct the box and to fully wrap the entire protein (see Table 1 for the ...
Liver fibrosis occurs during wound healing after repeated liver injury and is characterized by extensive extracellular matrix deposition. We previously identified hyaluronan synthase 2 (HAS2) as a driver of liver fibrosis and hepatic stellate cell (HSC)
Some examples include a ball rolling down an incline, a car moving on a road, an arrow shot from a bow, etc. Answer and Explanation: Given: Mass of the body, {eq}m =10\;kg {/eq} Velocity of the body, {eq}\displaystyle v = 4\;m/s {/eq} The formula ...
Melting of the Greenland ice sheet (GrIS) and its peripheral glaciers and ice caps (GICs) contributes about 43% to contemporary sea level rise. While patterns of GrIS mass loss are well studied, the spatial and temporal evolution of GICs mass loss and th
