Answer:
Explanation:
The acceleration of the motorcycle is given by Newton's second law:
where
F = 1295 N is the force applied to the motorcycle
m = 350 kg is the mass of the motorbike
a is the acceleration
By substituting the numbers into the formula, we find
Answer:
The net force acting on the otter along the incline is 13.96 N.
Explanation:
It is given that,
Mass of the otter, m = 2 kg
Distance covered by otter, d = 85 cm = 0.85 m
It takes 0.5 seconds.
We need to find the net force acts on the otter along the incline. If a is the acceleration of the otter. It can be calculated using second equation of motion as :
Here, u = 0 (at rest)
The net force acting on the otter along the incline is given by :
F = ma
F = 13.6 N
So, the net force acting on the otter along the incline is 13.96 N. Hence, this is the required solution.
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.
