Classical Mechanics
Calculate the work done by a long distance runner during a 10 km race. The mass of the runner is 52kg . Gravitational field strength is9.8N/kg
Classical Mechanics
We have a hollow sphere, 30cm diameter and 3mm thickness. total weight is 1,2 kg and material tensile strength is 570Mpa (83.000psi)
What is the theoretical Rpm limit it can withstand?
Ps. If more info is required please make an approximation.
Thank you

Alternating current have frequency of 50/60 Hz. it is audible sound. then why we cant hear it
Classical Mechanics
A bullet is fired through a board 11.7 cm thick, with a line of motion perpendicular to the face of the board. If the bullet enters with a speed of 381 m/s and emerges with a speed of 211 m/s, what is its acceleration as it passes through the board?

Classical Mechanics
Starting from rest on your bike, you go in a straight line with a=4m/s^2 for 2 seconds. Then you pedal at constant velocity for another 5s.
a) What's your final velocity
b) What is the total distance travelled

To qualify for the finals in a racing event, a race car must achieve an average speed of 250 km/hr on a track with a total length of 1600 m. If a particular car covers the first half of the track at an average speed of 225 km/hr, what minimum average speed must it have in the second half of the event in order to qualify?
