Question

A car weighing 800 kg starts from rest due to the force of the engine, which evenly

increases so that after the first second it has a value of 325 N. Calculate what speed it will havethe car after 10 s of movement and what path it took in that time.

Answer 1

Answer:4.0625m/s

Step-by-step explanation:

force(f)=325N

Time(t)=10seconds

Mass(m)=800kg

Initial velocity(u)=0

Final velocity(V)=?

F=(v-u) ➗ t

325=800(v-0) ➗ 10

325=800v/10

Cross multiplying we get

800V=325 x 10

800V= 3250

V=3250/800

V=4.0625m/s
