Jiminy Jones was driving his Aston Martin last night with constant speed of 120 km/h. He suddenly saw a big tree on his way, 100 m away and hit the brake. His car stopped
right before the tree. Determine:
The acceleration of the car. The amount of time it took the car to stop, after he hit the brake.

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?

Why are graphs useful when interpreting data

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
