The years 1609-1610, how many settlers were killed by Indians?

400 settlers

Explanation:

Instead of growing their own supply of corn (a New World crop unfamiliar to the English), the settlers relied heavily on corn grown by nearby Indians. But even with their neighbors' help, over 400 settlers would die over the winter of 1609-1610.

Explanation:

Given

mass (m) = 1500 kg

Velocity (v)= 30 m/s

Momentum = ?

we know that momentum is the product of mass and velocity so

Momentum = m * v

                   = 1500 * 30

                   = 45000 kg m/s

hope it helps :)
