Answer to Question #36766 in Electric Circuits for David

Question #36766
An object is thrown upward from the edge of a tall building with a velocity of 10 m/s. Where will the object be 3 s after it is thrown? Take g = 10ms^{-2} 15 m above the top of the building 30 m below the top of the building 15 m below the top of the building 30 m above the building 2 A stone thrown from ground level returns to the same level 4 s after. With what speed was the stone thrown? Take g = 10ms^{-2} 20 m/s 10 m/s 30 m/s 15 m/s 3 What is common to the variation in the range and the height of a projectile? horizontal velocity time of flight vertical velocity, horizontal acceleration vertical velocity horizontal acceleration 4 A cart is moving horizontally along a straight line with constant speed of 30 m/s. A projectile is fired from the moving cart in such a way that it will return to the cart after the cart has moved 80 m. At what speed (relative to the cart) and at what angle (to the horizontal) must the projectile be fired? 35.8 m/s at 24 degrees 38.6 m/s at 54 degrees 27 m/s at 35 degrees 2
