I need solve this assignment

Flying Circus of Physics- In 1939 or 1940. Emanuel Zacchini took his human-cannonball act to an extreme: After being shot from a cannon. he soared over three Ferris wheels and into a net {see the gure]. Assume that he is laUnched with a speed of 2? mr's and at an angle of 54\"- ial Treating him 35 a particle, calmiate his clearance ever the rst wheel. lb] If he reached maximum height over the middle wheel. by how much did he clear it? {c} How far from the cannon should the net's center have been positioned [neglect air drag]? Current Attempt in Progress An Earth satellite moves in a circular orbit 975 km above Earth's surface with a period of 104.4 min. What are [:1 the speed and M the magnitude of the centripetal acceleration of the satellite? [all Number Units I _ _ 3 QB {bl Number n When a large star becomes a supernova. its core may be compressed so tightly that it becomes a neutron star. with a radius of about 24.0 km {about the size of a typical city]. If a neutron star rotates once every 0.770 seconds. la) what is the speed of a particle on the star's equator and lb) what is the magnitude of the particle's centripetal acceleration? [c] If the neutron star rotates faster. do the answers to {a} and lb) increase. decrease. or remain the same? it) c
