Answer: 0.09 m
Explanation:
Centripetal acceleration in terms of tangential speed is:
where r is the radius.
It is given that,
centripetal acceleration of the mouse, 
tangential speed , 
Radius of salami is:
Thus, the radius of the salami is 0.09 m.

ANSWER:
F(h)= 230 N is the horizontal force you will need to move the pickup along the same road at the same speed.
STEP-BY-STEP EXPLANATION:
F(h) is Horizontal Force = 200 N
V is Speed = 2.4 m/s
The total weight increase by 42%
coefficient of rolling friction decrease by 19%
Since the velocity is constant so acceleration is zero; a=0
Now the horizontal force required to move the pickup is equal to the frictional force.
F(h) = F(f)
F(h) = mg* u
m is mass
g is gravitational acceleration = 9.8 m/s^2
200 = mg*u
Since weight increases by 42% and friction coefficient decreases by 19%
New weight = 1+0.42 = 1.42 = (1.42*m*g)
New friction coefficient = μ = 1 - 0.19 = 0.81 = 0.81 u
F(h) = (0.81μ) (1.42 m g)
= (0.81) (1.42) (μ m g)
= (0.81) (1.42) (200)
= 230 N
Answer:
$416 sounds like the best answer.
Explanation:
The tickets started off at $17, but a $4 discount for EACH ticket bought.
so 17-4 is 13
now tickets cost $13 each.
Multiply it by 32.
13x32=416
