2) Shuttle astronauts climb at a rate of 24.5m/s^2 shortly after takeoff. What apparent weight would a 95kg astronaut have during this phase of the ascent?

3) A golf cart with driver has a mass of 320kg and accelerates at 1.4m/s^2. Assuming the force does not change, what would be the acceleration if a 70kg passenger gets on board?

Note: The problem asks DURING the fall

2) (M + a)*g

3) F = 320*3.2 = (320 + 70)*a'

Solve for a'
