A 40.0-kg projectile is fired at an angle of 30.0° above the horizontal with an initial speed of 142 m/s from the top of a cliff 124 m above level ground, where the ground is taken to be y = 0. (a) What is the initial total mechanical energy of the projectile? (Give your answer to at least three significant figures.)
4.3 Projectile Motion University Physics Volume 1The time for projectile motion is determined completely by the vertical motion. Thus, any projectile that has an initial vertical velocity of 21.2 m/s and lands 10.0 m below its starting altitude spends 3.79 s in the air. (b) We can find the final horizontal and vertical velocities . and . with the use of the result from (a).
A 20.0-kg projectile is fired at an angle of $60.0^{\circ A 20.0-kg projectile is fired at an angle of. 60. 0 . 60.0^ {\circ} 60.0. above the horizontal with a speed of 80.0 m/s. At the highest point of its trajectory, the projectile explodes into two fragments with equal mass, one of which falls vertically with zero initial speed. Ignore air resistance.
4.11 Mechanical Energy & Thermal Energy AnswersA 0.145 kg copper projectile, with a Specific Heat Capacity of 387 J/(kg * C o), hits a titanium plate moving at 15.6 m/s. If all of the KE of the projectile is converted into thermal energy of the projectile, what is the increase in temperature of the projectile? m = 0.145 kg c = 387 J/(kg * C o) v o = 15.6 m/s v f
Projectile B or Projectile C or Therefore only projectile A 100-kg projectile crashes through a castle wall with a kinetic energy of 266.45 kJ. What was the speed of the projectile? The trebuchet below has a 4,500 kg counterweight and throws a 40 kg projectile along the path that is shown, for a total distance of 25 m.
MCQ in Engineering Mechanics Part 8 ECE Board ExamFeb 06, 2020 · A 40 kg block is resting on an inclined plane making an angle of 20° from the horizontal. If the coefficient of friction is 0.60, determine the force parallel to the incline that must be applied to cause impending motion down the plane.
5. Projectile MotionThe Range R of a Projectile:Another kind of projectile problem is picture below. The ground is flat throughout the trajectory of the projectile. Also suppose 1. the magnitude of the initial velocity is V 0 = 35mês and 2. the direction is initially an angle q=30° above the horizontal direction. (Obviously, these numerical values can be
A projectile of mass 2 kg is shot from a cannon at an A projectile of mass 2 kg is shot from a cannon at an initial angle of 30 degrees above the horizontal with an initial speed of 40 meters per second. Assume that the ball is shot from the origin. A.

Part B The acceleration is always pointing downwards with a constant value of 9.8 m/s2 . Projectile Motion Ranking Task . Part A The case achieving the maximum height . Part B The case taking the longest time to hit the ground
Effect of Trebuchet Arm Length or Counterweight Mass on Jun 23, 2020 · Figure 3. Schematic you can use to start analyzing the physics of a trebuchet. Note that m 1 and m 2 can be treated as point masses (so you do not need to account for their diamters), but are drawn larger in the figure. The variables in Figure 3 are as follows:m1 is the mass of the counterweight in kilograms (kg).
Student Exploration:TrebuchetCounterweight is 4500 kg, Payload is 160 kg, Fulcrum is 9.0 m, Short arm is 3.0 m, Long arm is 9.0 m, Sling is 5.0 m, and Prong angle is 40°. Introduction:Once the payload is in the air, it is called a projectile. In this activity, you will see how each dimension of the trebuchet affects the angle and speed of the projectile.
