What is the formula for time? (something like speed * distance=time?) ?

Three students derive the following equations in which x refers to distance traveled, v the speed, a the acceleration (m/s^2), and t the time, and the subscript (0) means a quantity at time t=0: a) x=vt^2 + 2at, b) x=v0t+1/2at^2, and c) x=v0t+2at^2.

How does a thunderstorm break apart and disappear?

Airplane A, starting from rest with constant acceleration, requires a runway 400 m long to become airborne. Airplane B requires a takeoff speed twice as great as that of airplane A, but has the same acceleration, and both planes start from rest.

If conducted accurately, identical investigations should produce similar results. Sometimes, errors, like measurement errors, can cause differences in results.

Object A with a mass of 500 kilograms hits stationary object B with a mass of 920 kilograms. If the collision is elastic, what happens after the collision? A) Both object A and object B move forward but with different velocities.

If an injury is caused by impact from an object alone, is this considered a caught-in or - between incident? Select the best option No, this is a struck-by incident Yes No, this type of incident is undefined
