Question

1. It's a short question but its physics is very interesting :)

Planes bank in a turn. Why?

2. How can you describe the acceleration in such cases:

a- when the speed is constant (ex. ? = 30 rad/s)

b- when the speed varies according to (? = 5*t. rad/s, where t is time is seconds)

**Answers need to be in your own words** Nice and short please thank you.

Answer 1

1)A banked turn (aka. banking turn) is a turn or change of direction in which the vehicle banks or inclines, usually towards the inside of the turn. For a road or railroad this is usually due to the roadbed having a transverse down-slope towards the inside of the curve. The bank angle is the angle at which the vehicle is inclined about its longitudinal axis with respect to the plane of its curved path.

2) a)acceleration=0 bcoz accleration is a change of speed(velocity)

b) a=dw/dt=5 rad/s^2
