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

Thank you

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

not too sure thinking all accelerations are pointed down
