Answer:
a= 1.81 m/s²
Explanation:
Ratio of the weights on both surfaces can be calculated as,
=
Here;
Wa is the weight on the asteroid,
is weight on earth,
m is mass of pack, a is acceleration due to an asteroid and
g is acceleration due to gravity.
Rearrange above equation for a,
a=g (
)
Substitute 3.24 N for Wa, 17.5 N for
,
9.81 m/s² for g in the above equation,
a= 9.81(
)
a= 1.81 m/s²
Because they have special tool's that help them find out
12m/s
Explanation:
Given parameters:
Distance run by student = 120 meters
Time = 10 seconds
Unknown:
Speed = ?
Solution:
Speed is the rate of change of distance with time:
Speed = 
Now input the parameters:
Speed =
= 12m/s
