A student is sitting on the right side of a school bus when it makes a 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. a force parallel to the seat directed forward on the student.
b. a force parallel to the seat directed to the right on the student.
c. a force parallel to the seat directed to the left on the student.
d. no other force on the student. e. a force parallel to the seat in a direction between forward and left on the student.
