A boy pushes forward a cart of groceries with a total mass of 40.0 kg. What is the acceleration of the cart if the net force on the cart is 60.0 N?

1.5m/s2

F=ma

a=F/m

a=60/40

a=1.5m/s2

f is prop to m1xm2 double m1 double force

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
