Answer:
<u>Circular Motion:</u>
When an object is moving with a uniform circular motion, it has a net acceleration,α which is directed towards the center of the circle.
Explanation:
<u>An object in a circular motion:</u>
When an object is moving in a circular motion, there speed is uniform across all the points on the circular path. While the change in acceleration is just because of the change in direction during the motion of the object. The force acting on the body is the centripetal force, Fc. As the force,Fc is directed towards the center of the circle and the different points on which the objects are present during the whole duration of motion is tangent to the center of the circle.
Answer:
The average net force on the truck is 375 Newtons.
Explanation:
Using Newton's 3rd equation of motion, we have :
×a×s
where, v = final velocity = 25 m/s
u = initial velocity = 20 m/s
a = acceleration
s = distance traveled = 300 m
Using these values in the above equation, we get acceleration = 0.375 m/
Using Newton's second law, we have:
F=m×a
where m = mass = 1000 kg
a= acceleration = 0.375 m/
Putting values we have F=375 N
