I attempted the qn .. but I'm not sure if this is the correct way of going about it..
the relevant equations used weren't given.
Force and Impulse:
The magnitude of an unbalanced force on a 10 kg object increases at a constant rate from 0N to 50N in 4.0s, causing the initially stationary object to move.
What is the speed of the object at the end of the 4.0s?
[not sure] ..
mv = Ft ??
v = Ft / m = (50N)(4.0s) / (10kg) = 20m/s
Thanks for any help = ) very appreciated
