Congrats chicho
Answer:
Distance covered by a car is 32 metre
Force acting on it is 12 metre
Explaination:−
According to the question
It is given that
Intial velocity, u = 0m/s
Finial velocity ,v = 16m/s
Time taken,t = 4s
Mass of cart,m = 3kg
We need to calculate the force acting on it .
Firstly we calculate thr acceleration of the car..
Using kinematics Equation
v=u + at
Putting all the value we get
a= 4m/s²
So the acceleration of the car 4m/s²
As we know the force is calculated by thr product of mass and acceleration..
F=ma
Substite thr value we get
◇ F = 3×4
◇ F = 12n
Hence the force acting is 12 Newton
Now calculating the distance covered by car in given condition
Using kinematic equation
v²=u²+2as
Substitute the value we get
◇16²=0²+2×4×s
◇256=2+8
◇256=3×s
◇s=356/8
◇s=32m
Hence the distance covered by the car is 32 metre.
thank you so much Didi monkey
