The ratio of an object's weight on Earth to its weight on Mars is 5 to 2. How much would a man, who weighs 145 pounds on Earth,
butalik [34]
To answer this youd have to set up a proportion. 5/2 is the ratio of weight on earth and mars respectively. The other side has to have the same ratio where 125lbs is the weight on earth and x is the weight on mars. The equation would look like 5/2=125/x. Youd have to cross multiply, and would get (125)(2)=5x. Solve for x to find the weight on mars

In this exercise, consider a particle moving on a circular path of radius b described by r(t) = b cos(ωt)i + b sin(ωt)j, where ω
Bingel [31]

Answer:

Acceleration of the particle = bw^{2}

Step-by-step explanation:

We are given the position vector of a particle moving in a circle of radius b units.

r(t) = b cos(ωt)i + b sin(ωt)j

Velocity , v =\frac{dr}{dt} = -bω sin(ωt)i + bω cos(ωt)j

The magnitude of velocity, v =\sqrt{v_x^{2} +v_y^{2} }

Squaring both sides,

v^{2} = b^{2} w^{2}(sin^{2}(wt)+cos^{2}(wt))

Since sin^{2}(wt)+cos^{2}(wt)) = 1

v^{2} = b^{2}w^{2}

The acceleration towards the centre is called the centripetal acceleration and is given by

a = \frac{v^{2} }{r}

a = \frac{b^{2}w^{2}}{b}

a = bw^{2}
