Suggest a method by which he could move himself away from this position, and explain the physics involved.
- Determine the magnitude of the y-component of force Q (N) if P=108.8 N, Q = 72.5 N , θ= 42.25° and α = 43.45°. Round off only on the final answer expressed in 3 decimal places. Instead of units, indicate the direction of the y-component.Why is the following situation impossible? An astronaut, together with the equipment he carries, has a mass of 150 kg. He is taking a space walk outside his spacecraft, which is drifting through space with a constant velocity. The astronaut accidentally pushes against the spacecraft and begins moving away at 20.0 m/s, relative to the spacecraft, without a tether. To return, he takes equipment off his space suit and throws it in the direction away from the spacecraft. Because of his bulky space suit, he can throw equipment at a maximum speed of 5.00 m/s relative to himself. After throwing enough equipment, he starts moving back to the spacecraft and is able to grab onto it and climb inside.A hammer of mass m = 0.455 kg is moving horizontally at a velocity of v = 4.5 m/s when it strikes a nail and comes to rest after driving the nail a distance Δx = 1.2 cm into a board.

The data collected in the field indicate that the vehicles stuck and skidded together a length of 25 m on the pavement whose dynamic friction coefficient is μk = 0.30. Considering that the masses of vehicles A and B are 2300 kg and 1500 kg, respectively, specify which of the cars was speeding at the moment of impact and by how much it exceeded the speed limit. Express your result in km / h for the purposes of the expertise.
