A small bag of sand is released from an ascending hot‑air balloon whose constant, upward velocity is ?0=2.15 m/sv0=2.15 m/s. Knowing that at the time of the release the balloon was 58.8 m58.8 m above the ground, determine the time ?τ it takes for the bag to reach the ground from the moment of its release. Use ?=9.81 m/s2.
An object is moving with an initial velocity of 5.8 i m/s and a final velocity 13.8 i m/s. The time taken for acceleration is 2.2 seconds. Calculate the acceleration in m/s2 to 2 sf. In your answer, you do not enter the i unit vector, but you do need to enter negative signs, if appropriate. e.g. if your answer is a = -5.4 i m/s,2 you would enter -5.4
A ball is thrown from a rooftop with an initial downward velocity of magnitude vo = 4.9 m/s. The rooftop is a distance above the ground, h = 29 m. In this problem use a coordinate system in which upwards is positive. A: Find the vertical component of the velocity, vfy, in meters per second, with which the ball hits the ground. B: If we wanted the ball's final speed to be exactly 27.3 m/s, from what height, hnew (in meters), would we need to throw it with the same initial velocity? c: If the height is fixed at 29 m, but we wanted the ball's final speed to be 32.7 m/s, what would the vertical component of the initial velocity viy need to be, in meters per second?
