1935.5 N is the "net force" acting on a car.
<u>Explanation</u>:
Given that,
Mass of the car is 790 kg.
Velocity of the car is 7 m/s. (v)
It turned around with 20 m. (r)
We know that, Net force = m × a
Now, Net force = m × a
Net force = 790 × 2.45
Net force = 1935.5 N
Answer:
Torque,
Explanation:
Given that,
Position of the flea,
Force acting on the flea,
We need to find the net torque about the origin on a flea located at coordinates. Its formula is given by :
On solving the cross product of r and F, we get :
So, the net torque about the origin on a flea is . Hence, this is the required solution.
