· free fall is any motion of a body where gravity is the only forceacting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it.

A racing car has a mass of 1525kg. What is its kinetic energy if it has a speed of 108km/h

Reptile [31]

E = 1/2 m v^2

108000m /3600 = 30m/s

E = 1525 * 0.5 * 30 = 22875 J

In a vertical dive, a peregrine falcon can accelerate at 0.6 times the free-fall acceleration g (that is, at 0.6 g ) in reaching

anyanavicka [17]

The radius R of the turn is 1.984 km.

<u>Explanation:</u>

As the falcon is experiencing a centripetal motion, the acceleration exhibited by the falcon will be centripetal acceleration. The formula for centripetal acceleration is

$a=\frac{v^{2} }{R}$

Here a is the acceleration for centripetal motion, v is the velocity and R is the radius of the circular path.

As the centripetal acceleration is given as 0.6 g, the velocity is given as 108 m/s, then the radius of the path can be determined as

$0.6 \times 9.8=\frac{(108)^{2}}{R}$

$R=\frac{(108)^{2}}{0.6 \times 9.8}=\frac{11664}{5.88}=1983.67\ \mathrm{m}$

So, the radius of the turn is 1.984 km.
