Average speed = (distance covered) / (time to cover the distance)

                           =  (200 miles)  /  (5.5 hours)

                           =      (200/5.5)  mile/hour

                           =          36.4 miles per hour    (rounded)

Answer:

p = mv

Explanation:

  • The momentum of a body is defined as the product of its mass and velocity. Its physical symbol is 'p'.
  • The formula for momentum is given by

                               p = mv

         Where,

                                m -  the mass of the body in kg

                                v - velocity of the body in m/s

  • Therefore, the unit of momentum is expressed as the kg m/s
  • The momentum of a body is always associated with its motion. It is a vector quantity and it is directed in the direction of the velocity vector.
  • If a body is at rest, the momentum associated with the body is zero.
  • The momentum plays a significant role in the kinematics of the body. As similar to the energy conservation law, the total momentum of the body is conserved.

A 68.0-kg person jumps from rest off a 2.20-m-high tower straight down into the water. Neglect air resistance during the descent
Margarita [4]

Answer:

F= 1333.767\,N

Explanation:

The velocity of the swimmer just before touching the water is:

v = -\sqrt{2\cdot (9.807\,\frac{m}{s^{2}} )\cdot (2.20\,m)}

v \approx 6.569\,\frac{m}{s}

The average force exerted on the diver by the water is determined by the use of the Principle of Energy Conservation and the Work-Energy Theorem:

(68\,kg)\cdot (9.807\,\frac{m}{s^{2}})\cdot (2.20\,m) +\frac{1}{2}\cdot (68\,kg)\cdot (6.569\,\frac{m}{s} )^{2}-F\cdot(2.20\,m) = 0\,J

F= 1333.767\,N
