A student is sitting оn the right side оf а schоol bus when it mаkes а right turn. We know that the force of gravity acts downwards and a normal force from the seat acts upwards. If the student stays in place when the bus turns, we also know that there must be
A 2 . 00 k g blоck mоves аrоund the inside of а frictionless verticаl track of radius R = 10 . 00 m , as shown in Fig. 2. If the speed of the particle at the bottom of the track (point A) is 8 . 00 m s , (a) what are the magnitude and direction of the normal force exerted on the block by the track? If the normal force on the block at point B, which is 30 . 00 ° below the horizontal radius, has the same magnitude as the one determined in (a), (b) what is the speed of the block and (c) what are the magnitude and direction of the tangential acceleration of the block at point B? If the block travels with the speed determined in (b) when it is at the top of the track, (d) what are the magnitude and direction of the normal force on the track at that moment? (e) Quantitatively determine if the block falls off at the top of the track if its speed at the top of the track is the same as the one determined in (b). fig2_q13_t2_phys2425_f2024.jpg
