Question
a truck with a mass of 2100 kg travels at a constant speed of 75 km/h.
(a) What is the magnitude of the truck’s linear momentum?
kg·m/s
(b) What average force would be required to stop the truck in 7.5 s?
does this have to do with f=ma or not? help

Answers
(a) p=mv
km/h -> m/s !!!
(b)
F=ma=mv/t
km/h -> m/s !!!
(b)
F=ma=mv/t
