4. A lightweight drone (1.00 kg) is launched at 800 m high and moves upward at a constant velocity (while ignoring the effects of gravity only on the drone). The balloon, when measured at a horizontal distance from you, is about 1600 m away from you. At the moment when the drone moves, you shoot a bullet (weight =18 g) with an initial velocity of 1009 m/s at a fixed angle a, where sin a=3/5 and cos a= 4/5. (g = 9.8 m/s?)

Ignoring drag, what is the x-component of the acceleration of a projectile? Why?
A pilot performs an evasive maneuver by diving vertically at 310 m/s. If he can withstand an acceleration of 8.0 g without blacking out at what altitude must he begin to pull out of the dive to avoid crashing into the sea? Express your answer using two significant figures and include the appropriate units.
A bird flying at 45 m/s, 100 m above sea level, drops an acorn of 1 kg upon his unsuspecting victims below. A Southeasterly wind causes the acorn to accelerate at 10 m/s^2 with the wind. Where does the acorn land? Assume air resistance is negligible and a gravitational acceleration of 10 m/s^2.
Force F1 = 10 N @ 30 and force F2 = 8N @ 270 . Calculate the magnitude of F1 + F2 .

A hammer of mass m = 0.455 kg is moving horizontally at a velocity of v = 4.5 m/s when it strikes a nail and comes to rest after driving the nail a distance Δx = 1.2 cm into a board. What is the duration of the impact, assuming the acceleration is constant during this time period, in terms of the given variables? What was the average force exerted on the nail, in terms of the mass, initial velocity, and distance traveled? What was the average force, in newtons, exerted on the nail?
. At the local farm, you buy a flat of strawberries and place them onthe backseat of the car. On the way home, you begin to brake asyou approach a stop sign. At first the strawberries stay put, but asyou brake a bit harder, they begin to slide off the seat. Explain.
A ball is thrown from the top of a tower at an angle of 40o to the horizontal with an initial speed of 6.60 m/s. During its flight, the only force acting on the ball is the force of gravity. It takes 3.55 s until the ball hits the ground. How tall is the tower?
2. To promote their new album, BTS decided to launch a satellite into orbit that will intercept all airwaves and play their songs worldwide. To do this, he needs to mount a 200 [kg] satellite onto a 850 [kg] rocket. It blasts off vertically from a launch pad with a constant net upward acceleration of 3.80 [m/s2]. When it has reached a height of 680 [m], the satellite was released, and the rocket blew up shortly after, due to a system failure. Assume that the satellite was not damaged after the explosion. (a) What is the maximum height that the satellite will reach above the launch pad? (b) How much time will elapse after system failure before the satellite comes crashing down the launch pad?(c) How fast will the satellite be moving just before it crashes?
(II) You know your mass is 62 kg, but when you stand on abathroom scale in an elevator, it says your mass is 77 kg.What is the acceleration of the elevator, and in whichdirection?
The following situations imply that the net force on the object is zero, except:a. a satellite orbiting the earth at a constant speedb. a raindrop falling at its terminal velocity c. a car driving straight on a highway at a steady 100 km/hd. All of these choices imply zero net force.
