25 seconds (25 sec)
What is the direction and value (#) of the net force?
20 Newtons to the right (20 N --> )
Which letter on the graph shows the fastest movement?
C
Which letter shows the furthest distance from the starting location?
D
How much force is needed to make a 300 kg box accelerate at a rate of 6 m/s^2 ?
1800 kg x m / s^2 OR 1800 Newtons (1800 N)
What is the formula to calculate Force?
Force = mass x acceleration (F = m x a )
