Answer:
The centripetal acceleration is 30 m/s²
Explanation:
Given that,
Radius = 0.30 m
Acceleration = 2.0 rad/s²
Time = 5.0
We need to calculate the centripetal acceleration
Using formula of angular velocity
Where,
a = acceleration
t = time
Put the value into the formula
Using formula of centripetal acceleration
Hence, The centripetal acceleration is 30 m/s²
The most likely answer to this problem would be (1) more mass and more inertia.
A 15-kilogram cart at rest and a 5-kilogram box would make up a 20-kilogram cart and box that is at rest on a horizontal surface. The mass changed into something more, of course, as a result of combining the two object into one and by combining the two objects' mass, the inertia that it previously possessed as a cart by itself was increased when the inertia of the box was also combined to the cart.
Answer:
Useful Output = 35 J
Explanation:
The useful energy output of the car must be equal to the difference between the total input energy supplied to the car and the energy wasted by the car:
Useful Output = Total Input - Waste
where,
Total Input = 120 J
Waste = 85 J
Therefore,
Useful Output = 120 J - 85 J
<u>Useful Output = 35 J</u>
