[SOLVED] Magnitude - Distance
#1
The force of the wind on the sails of a sailboat is 390 N north. The water exerts a force of 180 N east. If the boat (including crew) has a mass of 270 kg, what are the magnitude and direction of its acceleration.
---------------------------------
390 N North, 180 N East.
m = 270 kg
I never know how to find the magnitude, can some one help or explain the magnitude to me ?
#2
A shopper in a supermarket pushes a loaded cart with a horizontal force of 10 N. The cart has a mass of 30 kg. HOw far will it move in 3.0 s, starting from the rest? (Ignore friction)
-----------------------------------
Horizontal F = 10 N
m = 30kg
t = 3 s
d = rt
v (initial) = 0
I only got to this point ?
Help please ? Thanks
