A ball is tossed upwards into the air with an initial upwards velocity of 3.0m/s. What is the ball's velocity when it returns to
krek1111 [17]
  • Same as initial velocity.
  • Acceleration due to gravity is 9.8m/s^2

Which is constant on the whole way of travel of the ball.

As no change in acceleration there is no change in velocity at end and it remains at 3m/s

List two advantages and two disadvantages to worldwide use of SI.
katrin [286]

Two disadvantages Retooling and conversion of machines and equipment in the US would be very expensive

Some expressions in the English language would eventually be quite strange: “A miss is as good as a mile”; “Inching along…”; “Ten gallon hat”; “The whole nine yards” & etc. Advantages everything is based on 10 so its easy to switch units

A 90.0-kg man runs at a constant speed of 11.5 m/s. what is his kinetic energy?
harina [27]

The kinetic energy possessed by the man is 517.5 Joules.

<u>Given the following data:</u>

  • Mass = 90.0 kg
  • Velocity = 11.5 m/s.

To find the kinetic energy of the man:

Kinetic energy is an energy that is possessed by a physical object or body due to its motion.

Mathematically, kinetic energy is calculated by using the formula;

K.E = \frac{1}{2} MV^2

<u>Where:</u>

  • K.E is the kinetic energy.
  • M is the mass of an object.
  • V is the velocity of an object.

Substituting the given values, we have;

K.E = \frac{1}{2} × 90 × 11.5

K.E = 45 × 11.5

<em>Kinetic energy = 517.5 Joules.</em>

Therefore, the kinetic energy possessed by the man is 517.5 Joules.
