Question

In the figure above, M1>M2, and both are sitting on a frictionless table. We can apply a horizontal force F from either the right or the left to move the two blocks. The magnitude of the force between masses M1 and M2 is You are pedaling a bicycle at 9.8m/s. The radius of the wheels of the bicycle is 51.9 cm. The magnitude of the angular velocity of the wheels is Blocks I and II, each with a mass of 1.0kg, are hung from the celling of an elevator by ropes 1 and 2. What Is the force exerted by rope 1 on block II when the elevator is accelerating downward at 1m/s2? (Take g=10m/s2.) A block with a mass M=4.85kg begins at rest at the top of a curved slide. There is no friction. The speed of the block after it has slid along the slide sufficiently far for its vertical drop to be 19.6 m is

Explanation / Answer

8) d) By Newton's third law will be equal in magnitude and opposite direction.

9) a) w = V / r = 9.8m / s / (0,519m) = 18.88 approximately 19 m / s

10) option C) ma = TW, T = m + w, T = 1kg x (-1m / s2) + 10m / s2 x 1kg = 9N

11) option a) 19,6m / s
