-208.34=10α
α= -20.83rad/s2(Correct)
0=52.08+α(10)
-52.08=10α
α=-5.208rad/s2 (Wrong)
Yes, the total time is 20 seconds. But that includes three segments:freshbox said:but it says
"and it takes a total of 20 seconds to stop at the pit from its top speed of 300km/h"
total =20 secs?
What formula? The attachment was blank.freshbox said:my book only has this formula.. no wonder i keep getting stucked..
That's the basic definition of speed, so sure.So S=d/t is the only way to solve?
Rotational motion is the movement of an object around a fixed point or axis.
The key components of rotational motion include angular displacement, angular velocity, and angular acceleration.
Rotational motion involves movement around a fixed point, whereas linear motion involves movement in a straight line.
Angular velocity is the rate of change of angular displacement, while linear velocity is the rate of change of linear displacement. The two are related by the equation v = rω, where v is linear velocity, r is the radius, and ω is angular velocity.
Torque is the measure of the force that causes an object to rotate around an axis. It is directly proportional to the angular acceleration of an object and is represented by the equation τ = Iα, where τ is torque, I is moment of inertia, and α is angular acceleration.
