2. an archer shoots an arrow at 83.0 m/s at a 62.0 degree angle. if the ground is flat, how much time is the arrow in the air?
Answers: 3
is the angle, t is the time and g is the acceleration of gravity
.
, and:
when it goes back to the ground. We need to find that time

Aparticle of mass m is projected with an initial velocity v0 in a direction making an angle α with the horizontal level ground as shown in the figure. the motion of the particle occurs under a uniform gravitational field g pointing downward. (a) write down the lagrangian of the system by using the cartesian coordinates (x, y). (b) is there any cyclic coordinate(s). if so, interpret it (them) physically. (c) find the euler-lagrange equations. find at least one constant of motion. (d) solve the differential equation in part (c) and obtain x and y coordinates of the projectile as a function of time. (e) construct the hamiltonian of the system, h, and write down the hamilton’s equations (canonical equations) of motion.
