Answer:

129.78m

Explanation:

The following data were obtained from the question:

θ = 16.9°

U = 48.3m/s

g = 10m/s2

R =?

R = U^2 Sin2θ / g

R = (48.3)^2 Sin33. 8/ 10

R = 129.78m

When you skid to a stop on your bike, you can significantly heat the small patch of tire that rubs against the road surface. Sup
Wittaler [7]

Answer:

W_f = 148.17J

Explanation:

During the exchange of applied force, thermal energy is generated by the friction that exists between the ground and the tire.

Said force according to the statement is the reaction of half the force on the rear tire. In this way the normal force acted is,

N=\frac{mg}{2} = \frac{90*9.8}{2} = 441N

The work done is given by the friction force and the distance traveled,

W_f = fd = \mu_k Nd

Where \mu_k [/ tex] is the coefficient of kinetic frictionN is the normal force previously found d is the distance traveled,Replacing,[tex]W_f = (0.80)(441)(0.42)

The thermal energy released through the work done is,

W_f = 148.17J

marissa [1.9K]

Answer:

k = 1,250 N/m

Explanation:

Use the formula F=kx, with F=5N and x=0.04m

Then the spring constant (k) is 5/0.04
