1.) A ball is thrown horizontally from a height of 1 m and lands 5 m away. a. What is the time of flight of the ball?

b. What is the initial velocity of the ball?

2.) A potato gun is fired horizontally from a height of 1.5 meters with the potato launched at 25 m/s.

a. What is the time of flight of the potato?

b. How far from the gun will the potato land?

3.) A water park is designing a new water slide that finishes with the rider flying horizontally off the bottom of the slide. The slide is designed to end 1.2 m above the water level, and the average rider is estimated to leave the bottom of the slide at 25 m/s. How far will the rider fly through the air before hitting the water?

4.) A marble rolls horizontally off a table that is 0.8 m tall. If the marble lands 0.6 m from the base of the table, what is the initial velocity of the marble?

5.) The launch velocity of a toy car launcher is determined to be 5 m/s. If the car is to be launched from a height of 0.5 m, where should a target be placed so that the toy car lands on it?

6.) A stunt car traveling at 20 m/s flies horizontally off a cliff and lands 39.2 m from the base of the cliff. How tall is the cliff?

7.) A blow dart is fired horizontally from a height of 1.2 meters. If the dart hits a target that is 0.6 m high and 12 m away, what is the initial velocity of the dart?

8.) A B-52 bomber jet flies at a horizontal velocity of 286.2 m/s and at an altitude of 7500 m above the ground. How far away horizontally should a payload be dropped to land on a target?

Somebody please help me... I'm so confused. If you do these questions, please include the steps and charts if there are any. I really need help. Thank you! Love ya!

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c.m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
