<span>First draw a free-body diagram. Torque T = Force F x Distance d where force is the component of gravitational force g and d is the lever arm distance to the pivot point. Since the pivot point is at the back tire we subtract that from the length of the car resulting in d = 1.12 - 0.40 = 0.72 meters = d. We are interested in the perpendicular component of the force exerted on the car jack so use sin 8 degrees then T=1130 kg x 9.81 m/s^2 x sin(8 degrees) x0.72 m = 1,110.80 Newton-meters</span>
In free fall, the only force acting on an object is gravity. The force of gravity is an unbalanced force, which causes an object to accelerate. In the absence of air, two objects with different masses fall at exactly the same rate of acceleration.
Explanation:
study of motion of an object ...plzz if anyone knies the correct meaning of it ..do comment
Answer:
4.4 km
Explanation:
t = Time taken
u = Initial velocity = 24 m/s (Assumed)
v = Final velocity
s = Displacement
a = Acceleration = -0.065 m/s² (Assumed)
Distance = Speed × Time
The train travels for 9600 m.
The Distance the train traveled when it slowed down is 4.4 km
True, because being a competitive person means that you like challenging yourself to do more things, but if you’re really competitive you might challenge yourself too hard, and might hurt yourself, which will make you not want to really compete with anything anymore
