13 of 10 pt A glider is gliding in a horizontal circle at a speed of 35 m/s. If the glider is tilted 25° to the horizontal, what is the radius of the circle (in m) in which it is flying? (See the figure.) Assume that the required force is provided entirely by an 'aerodynamic lift' that is perpendicular to the wing surface. (in m) 4, AO 1.96 × 102 BO 2.29 × 102 2.68 × 102 DO 3.14 x...
A 1.00-kg glider attached to a spring with a force constant 16.0 N/m oscillates on a frictionless, horizontal air track. At t = 0, the glider is released from rest at x = -2.50 cm (that is, the spring is compressed by 2.50 cm). (a) Find the period of the glider's motion. s (b) Find the maximum values of its speed and acceleration. speed m/s acceleration m/s2 (c) Find the position, velocity, and acceleration as functions of time.

Question 5 A leave falls from a height of 5 meters above the ground. It lands with a speed of 1 m/s. How much work did the air do on the leave?
Please answer both 4&5 asap thanks!!!
1. A 0.150-kg glider is moving to the right on a frictionless, horizontal air track with a speed of (nen m/s. It has a head-on collision with a 0.300-kg glider that is moving to the left with a speed of 2.20 m/s. Find the final velocity (magnitude and direction) of each glider if the collision is elastic 2.

You throw a frisbee of mass m = 0.5 kg, and radius
r = 0.1 meters, off of a hill, with initial translational
speed of v0 = 5 m/s, from a height of
h0 = 3 meters. The tangential speed of the edge
of the frisbee is equal to the initial translational speed, and
doesn't change as it travels through the air. Treat the frisbee as
a solid disk, and ignore air resistance.
a) What is the initial total Kinetic...
