Calculate the drag force acting on a 105 kg (including the bicycle) cyclist moving at 10 m/s, 20 m/s, an at 30 m/s. Use a drag coefficient of 0.8, a frontal surface area of 1.0 m2 , and a density of 1.0 kg/m3.

40N

160N

360N

Explanation:

The drag force can be calculated using the formula below

FD = 0.5CPAV²

The drag coefficient = c = 0.8

The frontal density = p = 1.0kg

The frontal surface area = A = 1.0

The velocity v = 10m/s, 20m/s, 30m/s

When V = 10m/s

Fd = 0.5(0.8)(1)(1)(10)²

Fd = 40N

When V = 20m/s

FD = 0.5(0.8)(1)(1)(20)²

FD = 160N

When V = 30m/s

FD = 0.5(0.8)(1)(1)(30)²

FD = 360N

momentum of soft ball three times less than baskey ball

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
