Aconical pendulum is formed by attaching a 50g mass to a 1.2m string. the mass swings around the circle of radius 25cm (a) calculate the speed of the mass (b) acceleration of the mass (c) tension in the string

An uplifted block of rock between two normal faults

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?

Which type of reaction is shown in this energy diagram ?
