Answer:
30 m/s
Explanation:
Velocity is
since we know that the initial velocity is 0, and the acceleration is
then we also know that time is 3 seconds it follows that: 
Answer:
1.29 N
Explanation:
The equation for force (with work and distance) is:

We can plug in the given values into the equation:

okay u need to use the equation m=Fnet/a. Fnet=540N a=7.74m/s^2 m=540N/7.74m/s^2=69.77kg

Work = Force x distance
(10 pounds)(2 feet)
Work = 20 foot-pounds of work
hope this helps :)
