Explanation:
Perspective- the art of drawing solid objects on a two-dimensional surface so as to give the right impression of their height, width, depth, and position in relation to each other when viewed from a particular point.
Answer:
The change in the car's momentum is equal to -8910 kgm/s.
Explanation:
Given that,
The mass of a car, m = 990 kg
Initial speed, u = 22 m/s
Final momentum, v = 13 m/s
We need to find the change in the car's momentum. The change in momentum of the car is given by :
So, the required change in the car's momentum is equal to -8910 kgm/s.
Explanation:
It is known that it does not matter at what angle the force has been applied on an object because they all are acting perpendicular to the axis.
And, expression for torque from each force is as follows.
where, F = magnitude of force
r = distance from the center
Total torque will be calculated as follows.
Nm
= 3.9 Nm
Therefore, we can conclude that the magnitude of the net torque on the wheel about the axle through the center of the object is 3.9 Nm.
