Find the force of a 600 kg car experiences accelerating from 10 km/hr to 35 km/hr in 3 seconds?

Given,

m=600 kg

u=10 km/hr

v=35 km/hr

t = 3 sec

a=?

F=?

To find a:

u=10 km/hr=5/18*10=25/6=4.16m/s

v=35 km/hr=5/18*35=175/18=9.72m/s

t=3 sec

Now we have,

u=4.16m/s

v=9.72m/s

t=3 sec

To find acceleration:

a = (v-u) / t

a = (9.72-4.16) / 3

a=5.56/3

a=1.85m/s^2

To find F:

m=600 kg

a=1.85 m/s^2

F=ma

F=600*1.85

F=1110N

Therefore, F=1110N
