A hot air balloon is descending at a constant speed of 5.00 m/s on a path inclined at 60.0 ° below the horizontal. What is the component of velocity along the ground? 60.0 5.00 m/s 4.33 m/s O 2.50 m/s 2.89 m/s O 5.77 m/s -4.33 m/s
A ball of mass 0.3 kg, initially at rest, is kicked directly toward a fence from a point 20 m away, as shown below. The velocity of the ball as it leaves the kicker’s foot is 17 m/s at angle of 47 ◦ above the horizontal. The top of the fence is 6 m high. The ball hits nothing while in flight and air resistance is negligible. The acceleration due to gravity is 9.8 m/s2 (meters/seconds/squared). 1) How far above the top of fence will the ball pass? Consider the diameter of the ball to be negligible. Answer in units of m. 2) What is the vertical component of the velocity when the ball reaches the plane of the fence? Answer in units of m/s.
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?

To celebrate her good performance on a physics test, Alice decides to break out a bottle of champagne. In order to avoid property damage, she takes the bottle outside to uncork it. The cork pops off the champagne bottle with a velocity of 12.0 m/s at an angle of 15° relative to the vertical. When the cork is released, Alice is holding the bottle such that the cork is 1.80 m above the ground. How far does Alice have to walk to retrieve the cork?
A small block travels up a frictionless incline that is at an angle of 30.0° above the horizontal. The block has speed 5.10 m/s at the bottom of the incline. Assume g = 9.80 m/s2. How far up the incline (measured parallel to the surface of the incline) does the block travel before it starts to slide back down?
A player hits a baseball, which has an initial velocity of 42 m/s. At the moment the ball is hit with the bat, the height of the baseball will be 0.22 m. The distance from the point of contact to the wall is 170 m. The baseball has an angle of 40 degrees with respect to the horizontal. The player will get a home run, if he or she hits the baseball pass the wall. The height of the wall is 6m. \\ a) Will the player get a homerun? if so, the by how much does the baseball clear the wall? b) Now assume that the wall is completely removed. Find the horizontal range and maximum height of the baseball. Also assume that the path of the baseball is symmetrical, so it lands at a location that is 0.22 m above the ground.

A small block has a horizontal velocity of 4.00 m/s as it slides off the edge of a table. The table is a vertical distance of 0.85 m above the floor. If g = 9.80 m/s2, how far does the block travel horizontally while it is in the air?
An airplane starts from rest on the runway. The engines exert a constant force of 78.0 kN on the body of the plane (mass 9.20 × 104 kg) during takeoff. How far down the runway does the plane reach its takeoff speed of 73.1 m/s?
A basketball player jumps straight up for a ball. To do this, he lowers his body 0.340 m and then accelerates through this distance by forcefully straightening his legs. This player leaves the floor with a vertical velocity sufficient to carry him 0.880 m above the floor. (a) Calculate his velocity (in m/s) when he leaves the floor. (b) Calculate his acceleration (in m/s2) while he is straightening his legs. He goes from zero to the velocity found in part (a) in a distance of 0.340 m. (c) Calculate the force (in N) he exerts on the floor to do this, given that his mass is 120 kg.
