How Do You Calculate Force and Acceleration in Physics Problems?

[dyandel3]

I have two question i can't figure out and need help.

1. how much force must be applied to accelerate a 10,000 kg space shuttle to counter the Earth's gravitational acceleration of 9.8 m/s2?

2. if your car goes from 0 to 55 miles per hour in 6 seconds, what is your acceleration?
