WebSo the speed of the center of mass is equal to r times the angular speed about that center of mass, and this is important. This you wanna commit to memory because when a problem says something's rotating or rolling without slipping, that's basically code for V equals r omega, where V is the center of mass speed and omega is the angular speed ... WebFor example, if the crate you try to push (with a force parallel to the floor) has a mass of 100 kg, then the normal force would be equal to its weight. W = m g = (100 kg) (9.80 m/s 2) = 980 N, W = m g = (100 kg) (9.80 m/s 2) = 980 N, perpendicular to the floor. If the coefficient of static friction is 0.45, you would have to exert a force ...

WebA spacecraft is in a 400 km altitude circular orbit about the Earth; the orbital plane has an inclination angle of 20 degrees with the equatorial plane. What is the 4 V required so that the spacecraft is placed into a 400 km altitude circular equatorial orbit about the Earth. Give a sketch to describe where on the orbit the burn should occur. WebA small block of mass 2 kg starts slipping down the incline from a point 5.8 m away from front end of the spring. The block compresses the spring by 20 cm, stops momentarily and then rebounds through a distance of 1 m up the incline. The spring constant of the spring ( in N/m) is (Take g=10 m/s2) cu boulder leeds resume template
