A rock is dropped from the top of a tower. When it is 40 meters above the ground velocity of 17 m/s. When its velocity is 24 m/s

eimsori [14]

Answer:

Option B is the correct answer.

Explanation:

Let us consider 40 meter above ground as origin.

Initial velocity = 17 m/s

Final velocity = 24 m/s

Acceleration = 9.81 m/s

We have equation of motion v² = u² + 2as

Substituting

24² = 17² + 2 x 9.81 x s

s = 14.63 m

Distance traveled by rock = 14.63 m down.

Height of rock from ground = 40 - 14.63 = 25.37 m = 25.4 m

Option B is the correct answer.

Suppose that the metal cylinder in the last problem has a mass of 0.10 kg and the coefficient of static friction between the sur

andrew11 [14]

Answer:

The speed maximum speed is $0.49ms^{-1}$

Explanation:

The centrifugal force always acts on the cylinder and move away the rotating platform from the rotational axis. so the centripetal force provide by the frictional force:

Therefore

$\frac{mv^{2} }{r} =u_{s} mg$

coefficient of static friction: $u_{s} =0.12$

mass of the cylinder: $m=0.10kg$ \

distance of the cylinder from the turntable: $r=0.20m$

$\frac{mv^{2} }{r} =u_{s} mg$

cross multiply to find v

$v^{2} =u_{s} rg\\v=\sqrt{u_{s}rg } \\v=\sqrt{0.12*0.20*9.80}\\ v=0.49m/s$
