The answers to these physics problems are from my textbook. I need help with getting to the answer. 1) an automobile manufacturer claims that its product will, starting from rest, travel 0.40 km in 9.00s. What is the magnitude of the constant acceleration required to do this? answer: 9.9 m/s^2 2) A stone is thrown from the top of a building with an initial velocity of 20 m/s downward. The top of the building is 60 m above the ground....

Answer in units of m/s. Fo tic av 012 10.0 points An object is thrown vertically up and attains an upward velocity of 50 m/s when it reaches one fourth of its maximum height above its launch point. What was the initial speed of the object? The acceleration of gravity is 9.8 m/s. Answer in units of m/s 013 10.0 points A rock is thrown downward from an unknown height above the ground with an initial speed of 13 m/s....

A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 80.2 m/s at ground level. The engines then fire, and the rocket accelerates upward at 4.10 m/s2 until it reaches an altitude of 1190 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of −9.80 m/s2. (You will need to consider the motion while the engine is operating and the free-fall motion separately.) (a)...

A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 79.0 m/s at ground level. The engines then fire, and the rocket accelerates upward at 4.20 m/s2 until it reaches an altitude of 930 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of -9.80 m/s2. (You will need to consider the motion while the engine is operating and the free-fall motion separately.) (a)...

A test rocket is fired vertically upward from a well. A catapult gives it an initial speed of 80.2 m/s at ground level. Its engines then fire and it accelerates upward at 3.80 m/s2 until it reaches an altitude of 930 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of -9.80 m/s2. (You will need to consider the motion while the engine is operating separate fronm the free-fall motion.) (a) How...

A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 80.4 m/s at ground level. The engines then fire, and the rocket accelerates upward at 3.90 m/s2until it reaches an altitude of 1090 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of −9.80 m/s2.

Why
is the answer B?
13) A toy rocket is launched vertically from ground level (y 0 m), at timet- 0.0 s. The rocket engine provides constant upward acceleration during the burn phase. At the instant of engine burnout, the rocket has risen to 72 m and acquired a velocity of 40 m/s. The rocket continues to rise in unpowered flight, reaches maximum height, and falls back to the ground. The maximum height reached by the rocket is closest to:...
