A 40 kg bear cub is floating on a log in the middle of a lake. It leaps horizontally from the 600 kg log. If the cub’s speed at the moment she left the log was 4.0 m/s determine the speed of the log.

List one type of erosion and describe how it happens?

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]

Your target variable is δf, the magnitude of the difference in frequency between the waves emitted from the sonar device and the waves received by the device after reflecting off the whale. write an expression for δf in terms of the relevant frequencies using the subscript notation introduced above.
