gravitational field. Assume a linear drag equal to -av (a is a positive constant) due
to the surrounding medium, and determine the trajectory r(t) in terms of m, a, u and
the gravitational acceleration g.

A basket of flowers of mass 3 kg is placed on a flat grassy slope that makes an angle θ with the horizontal. The coefficient of static friction between the basket and the slope is 0.45 and the basket is on the point of slipping down the slope. Model the basket of flowers as a particle and the grassy slope as a plane. Take the magnitude of the acceleration due to gravity, g, to be 9.8 m s−2 . State the forces that act on the basket. Draw a force diagram showing them, defining the symbols that you use to represent the forces and marking the sizes of the angles to show the directions of the forces. Take the unit vector i to point up the slope and the unit vector j to point upwards and perpendicular to the slope. Add these unit vectors to your force diagram.

A projectile is fired vertically from point A with an initial speed of 290 ft/sec. Relative to an observer located at B, at what times (find two times t₁ < t₂) will the line of sight to the projectile make an angle of 20° with the horizontal? Compute the magnitude of the speed of the projectile at each time. The magnitude of the drag deceleration is kv², where k= 3.1(103) ft-¹ and v is the speed in feet per second. The direction of the drag is opposite the motion of the projectile throughout the flight (when the projectile is moving upward, the drag is directed downward, and when the projectile is moving downward, the drag is directed upward). Answers: t₁ = B t₂ = 20⁰ 17.45 0.56 430' 290 ft/sec sec, |v|= sec, |v|= A ft/sec ft/sec
