Q2) the coordinates of a bird flying in the xy-plane are given by () = 2.4 + (3 − 1.2 2) (a) Calculate the velocity and acceleration vectors of the bird as functions of time.
(b) Calculate the magnitude and direction of the bird’s velocity and acceleration at = 2.

Astone is thrown into a pond. what happens to the amplitude of the resulting waves as they get farther from the point where the stone hit the water? explain.

Describe uniform velocity and variable velocity in short

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius 푅=0.381meters and mass 푀=3.1푘푔. initially 푚"is on the ground and 푚#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of 푚#just before it strikes the ground. assume the pulley bearing is frictionless.
