Answer:

Step-by-step explanation:
F=dp/dt
F=10*Accln
dp that is change in momentum=mv2-mv1
10(-2-10)=dp
dt=4sec
so Accln=(10*(-12))/40
=-3

whats the formula
p = mv
Right Now just Remember this eqn force=change in momentum/t

ok
I got

thank you
actually my sis gave me task to do this I m in 6 the std
