change in momentum equal to- 2000×54+2000×0/15
samirmaths:
force equal 7200N
ok thank you

hey dear your ans is here..
m=2000kg
u=54km/h =15 m/s
v=0
t=15 sec
now
change in momentum= m(v-u)= 2000(0-15)=
= -30000kg m/s
F = m(v-u)/t
= -30000/15
F = -2000N
m=2000kg
u=54km/h =15 m/s
v=0
t=15 sec
now
change in momentum= m(v-u)= 2000(0-15)=
= -30000kg m/s
F = m(v-u)/t
= -30000/15
F = -2000N
np thank you
what is the use of 54 km per hour
you're wrong
