The 30 kg slider block is moving to the left with a speed of 5 m/s when it is acted upon by the forces F1 and F2. If these loadings vary in the manner shown on the graph, determine the speed of the block at t = 6 s. Neglect friction and the mass of the pulleys and cords.
Only solve by swapping the F1 and F2 function plots (F1 is the blue graph and F2 is the green graph).
An asteroid is discovered to have a tiny moon that orbits it in a circular path at a distance of 115 km and with a period of 49.0 h. Find the escape velocity from the asteroid
Two stars in a binary system orbit around their center of mass. The centers of the two stars are 7.50 1011 m apart. What is the mass of the smaller star
An artificial earth satellite has a circular orbit of radius 5.91 106 m (which means it is orbiting approximately -450 km above the surface of the earth) in an equatorial plane. Find the satellite's instantaneous acceleration at time t. Magnitude? ..
1. Why did the Industrial Revolution take place in Britain first? What conditions existed in Britain that did not exist elsewhere? 2. Was the Industrial Revolution inevitable? Was it a spontaneous or a planned event? What were the alternatives to..
What is the tangential acceleration of a bug on the rim of an 11.00 in.-diameter disk if the disk accelerates uniformly from rest to an angular speed of 79.03 rev/min in 3.60 s? One second after the bug starts from rest, what is its centripetal accel..
A house is 50.0 ft long and28.0 ft wide, and has 8.0 ft highceilings. What is the volume of the interior of the house in cubicmeters and in cubic centimeters?
A parallel-plate capacitor is made of two flat metal plates pressed against a thin slab of dielectric material. The capacitor is connected to a power supply, and a potential difference of 80 V is applied to the plates. With the power supply discon..
