Building height: -78.4metros

2) desdea a height of 10 meters is thrown up an object with a second Velocis of 28metros on

Calculate:
a) speed to reach the floor
b) time to reach the floor
c) height reached

Results:

speed to reach the floor: -31.30 m / s

time to reach the floor: 6.5 sec

lifting height: 40 meters

3) Calculate the acceleration acquiring a 3kg object if it applies a force of 12 Newton Formula

used f = m. to

Resolved: 4 meters / second squared

4) calculate the mass of the alplicarle anObject if a force acquires an acceleration force 2kilogramo of 40 centimeters on second squared

Formula used: f = m . to

score: 5 utm

5) expressed in all three systems the force applied to an object of 2utm gives it an acceleration of 60 cm / second squared

Formula used: f = m. to
