Answer:
v=u+at
15=10+a x 5
15-10= 5a
5= 5a
a=1 m/sec^2
D) 61 beats per minute
Explanation:
We have to use the centripetal force equation
we need the radious so we have to isolate "r" and we get
replacing m=65 kg, v= 4.1 m/s and Fc=455N we get
The radius of the amusement park chamber is 2.4m
Solenoid I think.
