Solve what is asked on the problem. Show your complete and detailed solutions. 1. The initial speed of a cannon ball is 0.20 km/s. If the ball is to strike a target that is at a horizontal distance of 3.0 km from the cannon, what is the minimum time of flight for the ball? 2. A ball is thrown horizontally from the top of a building O.10 km high. The ball strikes the ground at a point 65 m horizontally away from and below the point of release. What is the speed of the ball just before it strikes the ground? For items 3-4. A projectile is fired at an angle of 60.0° above the horizontal with an initial speed of 30.0 m/s. 3. What is the magnitude of the horizontal component of the projectile's displacement at the end of 2 s? 4. How long does it take the projectile to reach the highest point in its trajectory?

Hey im stuck on this question You are on the plane neptune and want to determine the acceleration due to gravity, g. You have a stopwatch and a toy gun that can launch a ping pong ball vertically upwards with an initial velocity of 7.5 m/s. Describe, in words, how you would perform an experiment to determine the acceleration due to gravity. Be sure to describe the variables you would measure, the equations you would use and the assumptions you would make. Make sure to include a diagram of the physical situation, label know and unknown quantities with units, coordinate system. Please use grade 12 kinematics and label the variables as v1, v2, a (Acceleration), t (time), d (displacement) Thanks!
Projectile Motion and Relative Motion 1. You want to see if you can throw a rock across a ravine that is 19.4 m wide. The other side of the cliff is 5.9 m below your side. You throw the rock at 12.1 a. How much time does it take for the rock to travel the horizontal distance between the two edges of 45° above the horizontal. the ravine? b. What is the vertical position of the rock at this time?

Projectile motion A projectile is launched from the origin, which is a point 50 ft from a 30-ft vertical cliff (see figure). It is launched at a speed of 50√2 ft/s at an angle of 45° to the horizontal. Assume the ground is horizontal on top of the cliff and that only the gravitational force affects the motion of the object.a. Give the coordinates of the landing spot of the projectile on the top of the cliff.b. What is the maximum height reached by the projectile?c. What is the time of flight?d. Write the integral that gives the length of the trajectory.e. Approximate the length of the trajectory.f. What is the range of launch angles needed to clear the edge of the cliff?

Hi, below is the explanation to the problem cited. But I don't understand the answer to the last question #3: Determine its average acceleration during the 34.0 sec interval. I am lost; can you help? Thanks! A car initially traveling eastward turns north by traveling in a circular path at uniform speed as in the figure below. The length of the arc ABCis 214 m, and the car completes the turn in 34.0 s. An x y coordinate system is shown. Three points A, B, and C are shown on the graph. These points are joined by a dotted curve. Point A is on the negative y-axis, point C is on the positive x-axis, while point B is in the fourth quadrant IV at an angle of −35° with the x-axis. From point A the curve initially moves rightward along a circular path, curves upward to cross B and then meets C. An arrow indicating the velocity at point A points horizontally and to the right. An arrow indicating the velocity at point C points vertically upward. 1. What is the acceleration when the car is at…
