Answer:
Unit of precision for force is the Newton.
Explanation:
It is the official unit used to describe force in science and mostly abbreviated with the symbol N.
Dropping a bouncy ball and stretching a rubber ban.
Answer:
90 m
Explanation:
Acceleration, 
where v and u are final and initial velocities respectively, t is the time taken
Substituting 
for a, 4 m/s for u and 10 s for t then
1*10=v-4
v=14 m/s
From kinematic equations
Making s the subject then
