Chapter 2, Problem 2/163 Your answer is partially correct. Try again. As part of an unmanned-autonomous-vehicle (UAV) demonstration, an unmanned vehicle B launches a projectile A from the position shown while traveling at a constant speed of 30 km/h. The projectile is launched with a speed of 74 m/s relative to the vehicle. At what launch angle a should the projectile be fired to ensure that it strikes a target at C? Compare your answer with that for the case...

Do not include any units in your answer The 20-9 bullet is traveling at V = 1200 m/s when it becomes embedded in the 2-kg stationary_block. Determine (a) the velocity of the block and the bullet (same velocity) after the impact in m/s, Assume velocity of the block and the bullet after the impact is 14 m/s and the coefficient of kinetic friction between the block and the plane is M = 0.2. (b) Determine the time required for the...

Only one try left. Thought I knew it. Please use 5.8 lb.
The 5.8-lb cylinder is falling from A with a speed vA 10 ft/s onto the platform. The spring has an unstretched length of 1.75 ft and is originally kept in compression by the 1-ft long cables attached to the platform. Neglect the mass of the platform and spring and any energy lost during the collision. (Figure 1) ▼ Part A Determine the maximum displacement of the platform, caused...

1. Determine whether the statements below are true or false: a. [4 points) Two carts move in the same direction along a frictionless track, each acted upon by the same constant impulse. If Cart 1 has the twice the mass of Cart 2, then Cart 2 will have the greater change in linear momentum. b. [4 points) Any force component that causes a centripetal acceleration cannot change the translational kinetic energy of the object. c. [4 points) A...

Please report your answer to 2 significant figures. As shown below, a block of mass m = 0.37 kg is initially at rest on a frictionless inclined plane at height = 5m and pressed against a spring so that the spring is compressed by an amount x = 2.7 m. Using conservation of mechanical energy, please find the speed of the block after it has lost contact with the spring and has reached a height he = 14 m. The...

Chapter 07, Problem 009 Your answer is partially correct. Try again. The only force acting on a 1.3 kg canister that is moving in an xy plane has a magnitude of 4.5 N. The canister initially has a velocity of 2.3 m/s in the positive x direction, and some time later has a velocity of 4.0 m/s in the positive y direction. How much work is done on the canister by the 4.5 N force during this time? Number1035 Units...
