No wait. I'm pretty sure you have.
Weight = (mass) · (gravity)
Weight = (10 kg) · (9.8 m/s²)
Weight = (10 · 9.8) kg·m/s²
Weight = 98 Newtons

Answer:
Acceleration: 
Explanation:
The acceleration of an object is equal to the rate of change of velocity:

where
u is the initial velocity
v is the final velocity
t is the time taken for the velocity to change from u to v
For the space probe in this problem, we have:
u = 100 ft/s (initial velocity)
v = 5000 ft/s (final velocity)
t = 0.5 s (time taken)
Therefore, the acceleration is
