The world long jump record is 8.95 m (Mike Powell, USA, 1991). Treated as a projectile, what is the maximum range obtainable by a person if he has a take-off speed of 9.5 m/s? State your assumptions.

Experiment 1 Measurement Mukesh Ghimire Lab Partner: Christopher Dorroh Abstract The main objectives of this experiment are to learn to measure the fundamental quantities of mechanics (length, mass, and time), derived quantities such as density and volume, and learn to use graphics software by determining the relationship between circumference and diameter of a circle. The equipment used in the experiment were: 1. Vernier caliper 2. Stopwatch 3. 30cm ruler 4. Meter stick 5. Wooden block 6. Metal object 7. Dialogram balance 8. Masses of various values 9. 5 circular objects of various sizes A distance of one meter was assumed with the help of arm and it was compared with the actual distance measure by ruler. A time interval of 30 and 60 seconds were assumed and the error was calculated. Also, the masses of lighter and heavier objects were assumed. To calculate volume, a wooden block was measured with Vernier caliper. Density of the metal object was calculated by measuring its mass using the dialogram balance, and by measuring its sides using Vernier caliper. The sources of uncertainty were the uncertainty of the instruments such as Vernier caliper, ruler, dialogram balance, used in the experiment.
