Answer: 2.70 cm

Given:

Density, d=9.32 g/cm^{3}

Mass, m=184 g

Formula Used:

Volume, V = density/mass

=\frac{184g}{9.32g/cm^{3}}\\ \Rightarrow V=19.7 cm^{3} \\ volume of cube = a^{3} where a is the side of the cube

a=19.7cm^{3} \\ \Rightarrow a=(19.7)^{(1/3)}\\ \Rightarrow a=2.70 cm

hence, the length of one side of silver cube is 2.70 cm

On a touchdown attempt, 95.00 kg running back runs toward the end zone at 3.750 m/s. A 113.0 kg line-backer moving at 5.380 m/s
dsp73

Answer:

(a) 1.21 m/s

(b) 2303.33 J, 152.27 J

Explanation:

m1 = 95 kg, u1 = - 3.750 m/s, m2 = 113 kg, u2 = 5.38 m/s

(a) Let their velocity after striking is v.

By use of conservation of momentum

Momentum before collision = momentum after collision

m1 x u1 + m2 x u2 = (m1 + m2) x v

- 95 x 3.75 + 113 x 5.38 = (95 + 113) x v

v = ( - 356.25 + 607.94) / 208 = 1.21 m /s

(b) Kinetic energy before collision = 1/2 m1 x u1^2 + 1/2 m2 x u2^2

                                               = 0.5 ( 95 x 3.750 x 3.750 + 113 x 5.38 x 5.38)

                                               = 0.5 (1335.94 + 3270.7) = 2303.33 J

Kinetic energy after collision = 1/2 (m1 + m2) v^2                

                                                = 0.5 (95 + 113) x 1.21 x 1.21 = 152.27 J
