Answer:
F = 339.23 N
Explanation:
Weight of a car, W = 1050 N
Initial velocity, u = 0
Final velocity, v = 42 m/s
Time, t = 13 s
The weight of an object is given by :
W = mg
g is the acceleration due to gravity
[tex]m=\dfrac{W}{g}\\\\m=\dfrac{1050}{10}\\\\m=105\ kg[/tex]
The force acting on car is :
[tex]F=ma\\\\F=\dfrac{m(v-u)}{t}\\\\F=\dfrac{105\times (42-0)}{13}\\\\F=339.23\ N[/tex]
So, the force acting on the car is 339.23 N.
