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
