1. ### a Martian rock weighs 15 Newtons on Mars. How much will it weigh on Earth? (The acceleration due to gravity on Mars is 3.7 m/ sec ^2)?

15 = 3.7 m/ sec ^2 mars       = 9.8 m/ sec ^2 earth 15 x 9.8 = We x 3.7 Weight in Earth = 39.7 Newtons Please Rate me Toast!!

3. ### A long jumper leaves the ground at an angle of 16.4 degrees to the horizontal and at a speed of 11.1 m/s.-?

Voy = Vo*sin 16.4 = 11.1*0.282 = 3.1 m/ sec   Vox = Vo*cos 16.4 = 11.1*0.959 = 10.6 m/ sec   range R = Vo^2/g*sin (16.4*2) = 123/9.806*0.542 = 6.80 m (angle is too small)

5. ### Mass on a Spring?

energy lost by friction FE = m*g*μ *x = 1.516*9.806*0.31*8*10^-2 = 0,369 joule  (1.68-0.369)*2 = 1.516*V^2 V = √ (1.68-0.369)*2 / 1.516 = 1.32 m/ sec
