An athlete swings a ball, connected to the end of a chain, in a horizontal circle. The athlete is able to rotate the ball at the
Alexandra [31]

Answer:

a) \omega _1=7.56rev/s=>47.5rads/s

b) a=30.7

c) a=35.91

Explanation:

From the question we are told that:

Initial angular velocity \omega _1=7.56rev/s=>47.5rads/s

Initial Length L_1=0.600m

Final angular velocity \omega _2=6.22rev/s=39rad/s

Final Length L_2=0.900m

a)

Generally the rotation with the greater speed is

\omega _1=7.56rev/s=>47.5rads/s

b)

Generally the equation for centripetal acceleration at 8.16 is mathematically given by

a=\omega_1^2*L_1

a=8.16 rev/s*0.6

a=30.7

c)

At 6.35 rev/s

a=6.35 rev/s*0.9

a=35.91

A girl is riding a bike with a velocity of 7 m/s. The bike undergoes an acceleration of 2 m/s2. What is the velocity of the bike
Dmitry_Shevchenko [17]

From the information provided, the velocity after 2 seconds is  11 m/s.

From the equations of motion;

v = u + at

Where;

v = final velocity

a = acceleration

t = time taken

The initial velocity of the bike was 7 m/s and its acceleration is  2 m/s2. This change occurred within a time of 2 seconds.

Hence;

v = 7 + 2(2)

v = 11 m/s

The velocity after 2 seconds is  11 m/s.
