Question

Help Immediately!!
if a 5000N force is applied to a 10,000kg object traveling at 10 m/s for 15 seconds, does the object come to a complete stop? have number to prove it please

Answer 1

force=mass x acceleration
5000=10000 x acceleration
5000/10000=acceleration
1/2=acceleration

v=u+at
where
v=final velocity
u=initial velocity
a=acceleration
t=time

lets find the time 't' when the body stops
so because the body stops v=0 and u is given as 10m/s and a is 1/2 we will take it as -1/2 cause the force is opposing the motion

so we have-
v=u+at
0=10-1/2t
-10=-1/2t
t=20secs

so the body doesn't stop in 15secs rather it stops after 20secs
