Answer:

Acceleration = 0

Explanation:

Initial velocity is the speed it starts going at. Final velocity is how fast it's going by the end. The acceleration is what changes the velocity. But if the acceleration is 0, the velocity will not change

When an object is moving with uniform circular motion, the centripetal acceleration of the object $\textbf{is\:Zero}$ .

Because the body is moving with a uniform velocity and hence, there might not be any acceleration due to it.

A basketball star exerts a force of 3225 n (average value) upon the gym floor in order to accelerate his 76.5-kg body upward. de

ryzh [129]

F = m . g = 76.5 x 9..8 = 749.7
Net Force = 3225 - 749.7 = 2475.3

F = m.a
2475.3 = 76.5 a

a = 32.35

V = at + v1
V = at + 0
V = 32.35 x 0.15
V = 4.8525

In a simple machine, the energy input is 120 J. If the efficiency of the machine is 80%, calculate the energy output

pashok25 [27]

Answer:

<h2>96 Joules</h2>

Explanation:

We know that efficiency is the ratio of output power by input power. i.e. Efficiency describes the quality of machine or system how good it is.
