A bicyclist of mass 88.0 kg puts all his weight on each downward-moving pedal as he pedals up a steep road. Take the diameter of

the circle in which the pedals rotate to be 0.33 m, and determine the magnitude of the maximum torque he exerts in the process.

Answer:

142.296 Nm.

Explanation:

Torque: This is the force that tend to cause a body to rotate or twist. The S.I unit of torque is Nm.

From the question,

T = F×r.................... Equation 1

Where T = Torque, F = Force, r = radius of the circle.

Note: F is the weight of the bicyclist.

Then,

F = W = mg............... Equation 2

Substitute equation 2 into equation 1

T = mgr................... Equation 3

Given: m = 88 kg, g = 9.8 m/s², r = 0.33/2 m

T = 88(9.8)(0.33)/2

T = 142.296 Nm.

Answer:

The height is : 60.025 m

Explanation:

The flowerpot falls off the balcony with zero launch angle

Given the time of fright as 3.5 s then ;

The formula to apply is ;

T=\sqrt{\frac{2H}{g} }\\\\3.5=\sqrt{\frac{2H}{9.8} }

3.5²= 2H/9.8

12.25 =2H/9.8

12.25 * 9.8 = 2H

120.05 = 2H

120.05/2 = H

60.025 =H

Gravity on Jupiter is 25 m/s/s, what is the weight of a 12 kg object on Jupiter?
stiv31 [10]

Answer:

300 Newtons

Explanation:

Weight is the force of attraction between two bodies, one usually larger (like a planet), and one smaller (like a person). Force can be calculated using the formula: Force = mass × acceleration.

The mass here is 12kg, the acceleration, which in this case, is the acceleration due to gravity is 25m/s/s, by plugging in our values, we have

Force = 12 × 25 = 300 Newtons or 300 N for short.
