High speed stroboscopic photographs show that the head of a 244 g golf club is traveling at 57.6 m/s just before it strikes a 45

almond37 [142]

Answer:

The speed will be "1.06 m/s".

Explanation:

The given values are:

Momentum,

m1 = 244 g

m2 = 45.2 g

On applying momentum conservation ,

Let v2 become the final golf's speed.

From Momentum Conservation

⇒ $Total \ initial \ momentum = Total \ final \ momentum$

⇒ $m1\times u1 + m2\times u2 = m1\times v1 + m2\times v2$

On putting the estimated values, we get

⇒ $0.244\times 57.6+0=0.244\times 39.9+45.2\times v2$

⇒ $57.844+0=9.7356+45.2\times v2$

⇒ $48.1084=45.2\times v2$

⇒ $v2=\frac{48.1084}{45.2}$

⇒ $v2=1.06 \ m/s$

A spherical ball of lead has a diameter of 7.5 cm . what is the mass of the sphere if lead has a density of 11.34 g/cm3? (the vo

Gwar [14]

The diameter of the sphere is 7.5 cm, therefore its volume is
V = [(4π)/3]*(7.5/2 cm)³ = 220.8932 cm³

The density of the lead ball is 11.34 g/cm³, therefore its mass is
m = (220.8932 cm³)*(11.34 g/cm³) = 2.5049 x 10³ g = 2.5048 kg

Answer: 2.5 kg (nearest tenth)
