Explanation:
Given :-
Distance covered by the truck = 400 m
Time taken to cover the distance = 20 s
Initial velocity of the truck = 0
To Find :-
The acceleration.
The force acting on it.
Analysis :-
Here, we are given with distance, time and initial velocity of the truck.
Firstly, using the second equation of motion find the acceleration accordingly.
Substitute the values with you in the formula of force and you can get the value easily.
Solution :-
We know that,
u = Initial velocity
a = Acceleration
f = Force
v = Final velocity
s = Distance
t = Time
Using the formula,
Given that,
Distance (s) = 400 m
Time taken (t) = 20 s
Initial velocity (u) = 0 m/s
Substituting their values,
400 = 0(20) + 1/2 (a) 400²
a = 2 m/s⁻²
Therefore, the acceleration is 2 m/s⁻².
Using the formula,
Given that,
Mass (m) = 7 tonnes = 7000 kg
Acceleration (a) = 2 m/s⁻²
Substituting their values,
f = 7000 × 2
f = 14000 N
Therefore, the force acting on it is 14000 N.
