- The position of a bird in the xy-plane is given by Bti + (yt-c t2)j where a = 1.2 m/s2, y = 2.4 and ß = -4.8 m/s. What is the bird's net acceleration at 2.0 s (magnitude and direction)? O 2.4 m/s? in the -y direction 7.2 m/s2 in the +y direction O 1.2 m/s? in the +y direction O7.2 m/s? in the -y direction 5.4 m/s2 in the +y direction O 5.4 m/s2 in the -y direction O 2.4 m/s2 in the +y direction O 1.2 m/s² in the -y directionV01For this problem think about a long jumper who takes off and lands from different heights. This is due to the Center of Gravity being higher when they leave the ground then when they contact the sand. If the jumper has a horizontal distance traveled of 7.5 meters and an initial horizontal velocity 6.1 m/s and a takeoff angle of 30 degrees. How far did the jumper fall vertically from takeoff to landing?
- T3.23 Please help me answer this physics question.You have put a sonar device at the top of a frictionless inclined plane, as shown in the diagram below. That device allows you to measure the distance an object is from the device, as well as the speed and the acceleration of that object. If we decide that the origin (h = 0) is at the sonar device, we want to know what the height change is as we slide down the incline. 0 For an angle below the horizontal of 6.46, we see that our object has slid a distance 1.13 m, as measured along the incline itself. Calculate the height change in meters - and report your answer as a negative number. (This value would be useful for calculating the change in gravitational potential energy, as we will do in the lab.) h=o 10% O i 26 QUATU 99+ hp X 55 83°F 3:11 PM 10/16/2022 Ctrl 0In my homework, I am asked to derive an equation for V0. The homework question is as follows: A howitzer fires a shell with a velocity of v0 at an angle Θ above the horizontal. The howitzer is on a plateau and the shell lands down in the plain below, a vertical distance d below the plateau and a horizontal distance L from where the howitzer is. Derive an expression for the magnitude of the initial velocity, V0, as a function of d, L, g, and Θ. Any help would be appreciated as I have worked on this problem for quite a while and I am not making progress.
- The best leader in the animal kingdom is the luma, which can jump to a height of 12 ft when leaving the ground at Ana angle if 45 degrees with what speed in si units must the animal leave the ground to reach that heightAsapYou're playing a cartoony racing video game, with a character on a motorcycle. You drive your character off a ledge at 15 m/s. The next ledge for the character's bike to land on is 25 m away (horizontally) and 12 m below. Assume the video game has realistic physics coded into it, except that acceleration due to gravity is only 8.0 m/s^2. a) will your character land on the next platform? b) whether they land or not, find their velocity (magnitude and direction) as they either land on or pass through the 12 m below position.
- A car is traveling south at 30 km/h. it rounds a curve, and 6 s later it is traveling west at 30 km/h. the magnitude of the average acceleration of the car is: (the answer is 7.1 km/h s ) I have the answer, but PLEASE show how to get it in step by step detail/explain how ( it's an exam review question but I don't know why that's the answer)A soccer player kicks a ball, while imparting spin to bend it. The ball starts on the ground and is kicked with an initial velocity of 15 ?/?, at an angle of elevation 30 degrees. Assume the ball was kicked north and the spin creates a constant acceleration ? to the west, which is what makes the ball follow a curved path. If the ball lands 8 meters west of the starting point, what is the value of ?? Assume the standard value of ? = 9.8 ?/?2.You are part of a car accident investigative team, looking into a case where a car drove off a bridge. You are using the lab projectile launcher to simulate the accident and to test your mathematical model (an equation that applies to the situation) before you apply the model to the accident data. We are assuming we can treat the car as a projectile.
