NS 4. A flying squirrel is gli ding (no wing flaps) from a tree to the ground at constant velocity. Consider air resistance. Diagram the forces acting on the squirrel.

Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.

At a pool, a 3.26 kg life ring is thrown by a lifeguard to a struggling swimmer. The lifeguard stand is 1.75 m above the water. If air resistance is negligible and the life ring is launch with a speed of 8.23 m/s at the angle indicated in the figure: a) Find the height of the life ring and the net force on the life ring at point P. b) Find how far the life ring lands from the base of the stand. c) With what velocity did the life ring strike the water at point Q? 30°

1 object with a mass of 1500 g (grams) accelerates 10.0 m/s> when an unknown force is applied to it. What is the amount of the force?

The question refers to a coin which is tossed straight up into the air. After it is released, it moves upward, reaches its highest point and falls back down again. Use one of the following choices (A through G) to indicate the force acting on the coin in the case described below. Answer choice J if you think that none is correct. Ignore any effects of air resistance. The coin is moving downward. A. The force is down and constant. B. The force is down and increasing C. The force is down and decreasing D. The force is zero. E. The force is up and constant. F. The force is up and increasing G. The force is up and decreasing O A O ΟΕ D OF O o J

At Ted's request, Bill pushes the pizza box across the granite countertop towards Ted. When the box leaves Bill's hand it is sliding at 2.60 m/s. The box comes to rest over a distance of 110 cm. What is the coefficient of kinetic friction, uk, between the pizza box and the countertop? (Ignore air drag.)
