You're driving your pickup truck around a curve that has a radius of 17 m.
creativ13 [48]

Answer:

v = 10.8 m/s^{2}

Explanation:

The centripetal force experienced by the steel toolbox is provided by the friction between the toolbox and the bed of the truck.

Therefore,

\frac{mv^{2} }{r} = f--------------------------------(1)

Here,

v - speed of truck

m - mass of toolbox

r - radius of curve around which the truck is turning

f - frictional force

f \leq μmg

In order to obtain Vmax, frictional force must also be max

Thus,

f = μmg--------------------------------------------------(2)

Substitute (2) in (1)

\frac{mv^{2} }{r} =  μmg

v^{2} =   μgr

g - 9.8 m/s^{2}

The standard value of coefficient of static friction between steel and steel is

μ ≈ 0.7

Therefore,

v = 10.8 m/s^{2}

You have just landed on Planet X. You take out a ball of mass 101 g , release it from rest from a height of 16.0 m and measure t
IRINA_888 [86]

Answer:

0.3817 N

Explanation:

Remark

One thing is certain: the ball has a mass of 101 grams wherever it is in the universe. That is not true of the force. The force on the moon is a whole lot less than it is on earth, and maybe planet x as well.

Givens

m = 101 g

vi = 0       That's what at rest means.

t = 2.91 s

d = 16 m

F= ?

Formulas

d = vi*t + 1/2*a * t^2

Force = m * a

Solution

16 = 0 + 1/2 a * 2.91^2

16 = 4.234 a                       Divide by 4.234

16/4.234 = a

a = 3.779

F = m * a

a = 3.779

m = 101 g = 1 kg / 1000 grams

m = 0.101 kg

F = 0.101 * 3.779

F = 0.3817N
