A)In attempting a broad jump an athlete generates a force equal to his double weight under a 45 degree angle to the horizon. What is his mass (measured in cm) and the launching angle? B)In a broad standing jump an athete generated on a distance of 65cm a force equal to his double weight under a 45 degree angle to the horizon. What is his mass (measured in cm) and the maximum height of this jump?

READING 2 Materials fracture when the force per unit area, called STRESS, exceeds a critical value. In general, the critical stress depends on the direction as well as the magnitude of the force. For example, bones break differently when subjected to torsional (twisting) stress than when subjected to compressional (or squeezing) stress. Let us consider compressional stress. Wet human bone for 20-39 year olds has...

Please don't attempt if you can not write a MATLAB
PROGRAM.
I don't need numerical physics solution, I need MATLAB code.
Read the question carefully
2) Falling Drops Imagine a solid sphere of diameter, d, falling through the air. After its release, the sphere accelerates until it reaches its terminal velocity. The terminal velocity is obtained when the drag force due to air friction, Fa, balances the weight of the sphere, W. The weight of the sphere is simply its...
