A wind turbine is initially spinning at a constant angular speed. As the wind's strength gradually increases, the turbine experiences a constant angular acceleration 0.172 rad/s2. After making 2870 revolutions, its angular speed is 151 rad/s. (a) What is the initial angular velocity of the turbine? (b) How much time elapses while the turbine is speeding up?

To practice Problem-Solving Strategy 3.1 Projectile motion problems. A ball thrown horizontally with speed viviv_i = 20.0 m/sm/s travels a horizontal distance of ddd = 58.0 mm before hitting the ground. From what height hhh was the ball thrown? If it takes a ball dropped from rest 2.900 s to fall to the ground, from what height H was it released? Express your answer in meters.
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....
