What is a unit of acceleration?<br> a. m/s<br> b. m/s2<br> c. m2/s<br> d. kg-m/s2

Basile [38]

A). m/s ... meters per second.
   That's a speed.

b). m/s² ... (meters per second) per second.
   Acceleration.

c). m²/s ... square meters per second.
   Rate of change of area.
   Meaningless unit, unless you happen to be
   a painter of houses or a mower of lawns.

d). kg-m/s² ... (mass) x (an acceleration).
      This is a unit of force.
   In fact, it's the definition of "newton".

A solid sphere has a radius of 0.200 m and a mass of 150.0 kg. how much work is required to get the sphere rolling with an angul

Allisa [31]

Here in this case we can use work energy theorem

As per work energy theorem

Work done by all forces = Change in kinetic Energy of the object

Total kinetic energy of the solid sphere is ZERO initially as it is given at rest.

Final total kinetic energy is sum of rotational kinetic energy and translational kinetic energy

$KE = \frac{1}{2}Iw^2 +\frac{1}{2} mv^2$
