You want to make a ride so you do not want to exceed 1.1g’s, if the radius of the turns are 10m, then what is the maximum speed
Citrus2011 [14]

The maximum speed is 10.4 m/s

Explanation:

For a body in uniform circular motion, the centripetal acceleration is given by:

a=\frac{v^2}{r}

where

v is the linear speed

r is the radius of the circular path

In this problem, we have the following data:

- The maximum centripetal acceleration must be

a=1.1 g

where g=9.8 m/s^2 is the acceleration of gravity. Substituting,

a=(1.1)(9.8)=10.8 m/s^2

- The radius of the turn is

r = 10 m

Therefore, we can re-arrange the equation to solve for v, to find the maximum speed the ride can go at:

v=\sqrt{ar}=\sqrt{(10.8)(10)}=10.4 m/s

Help me with the following problem
Effectus [21]

The mass of the ball is 1.55 kg and its change in momentum is  10 kgm/s.

<h3>What is momentum of a body?</h3>

The momentum of a body is the product of the mass and velocity of the body.

  • Momentum = mass * velocity

Mass of the ball = momentum/velocity

Mass of the ball = 3.29 / 2.11 = 1.55 kg

The change in momentum of the body or Impulse = force * time

Change in momentum of the body = 5.00 * 2.00 = 10 kgm/s

Therefore, the momentum of a body depends on its mass and velocity.
