Gr 11 Physics - Net Force?

Question

What is the net force accelerating a 5.0 kg cannonball from rest to 150m/s [W], if the applied force acts for 0.05s?

Answer 1

F=m*a
and
v(t)=v0+a*t

from the givens
150=0+a*0.05
a=3000 m/s^2

F=5*3000
F=15000 N

Answer 2

ordinarily, your physics area starts off without regard to friction. The tension utilized is meant to be from merely the weights. whether, you additionally can get prepare in deriving the stress utilized from the acceleration, employing F = MA.
