WebbThe inital velocity is going to be 'slowed' down to zero (m/s) because of gravity, and the effect will be equally the same returning. Therefore the acceleration/deaccelertion is equl, the distance is equal and so will the time. This will ultimately show that the velocity at the exact same elevation (height) will be the same. WebbIt is given that the object touches the ground after 5 seconds. h(t) represents the height of the object after 5 seconds, and so it is equal to 0, because the object then hits the ground. It is also given that the initial speed v_{0} = 64 ft/sec and t = 5 s. Substituting these values in the above equation we get. 0 = -16(5)^{2} + 64(5) + h_{0}
WebbEquate the initial mechanical energy to the mechanical energy. Solve for the unknown quantities. Check. Consider what the answer means. Check the units and that the answer makes sense. Reminder. This approach can only be used when the mechanical energy is conserved. Example: The ball is thrown straight upward and returns to its starting point. WebbGiven data:- Initial velocity, u = 147 m/s- Angle made with horizontal, θ1 = 60°- Angle made with horizontal after some time, θ2 = 45°We need to find the time taken to reach the inclination of 45°.Approach:We can use the equations of motion to solve this problem. Let's break the initial velocity into its horizontal and vertical components.Initial velocity, u = …
