- 6. A ball is thrown upward with a velocity of 4.5 m/s. Its speed and the magnitude of its acceleration at the highest point (a) are both equal to zero (b) are given by 9.81 m/s and 0 m/s², respectively (c) are given by 0 m/s and 9.81 m/s², respectively (d) cannot be predicted unless the height is known Answer: 7. Which of the following statements about a projectile is not true? Assume that the air resistance is negligible. (a) Its motion is in two dimensions. (b) The only acceleration is in the vertical direction. (c) Its velocity in the horizontal direction remains the same throughout the flight. (d) The velocity at the highest point of its trajectory is zero. Answer:A ball is thrown vertically upward with an initial speed v and reaches a maximum height y1. The same ball is thrown with an initial speed 3v to reach the maximum height y2. What is the correct relationship between y2 and y1? А. y2 = ½ y1 В. y2 = 2 y1 %D С. y2 = 4 y1 y2 = 9 y1 D.NASA has fired a rocket straight up into the air from ground level with an unknown initial velocity. It reaches a maximum height of 164,000 feet. This happened in Cape Canaveral therefore the rocket is under the acceleration of Earth's gavity in which we all know is -32 ft/sec/sec. Please round your answers to two decimal places. a). Find the time it takes for the rocket to reach maximum height. b). find the initial velocity necessary to reach that height.

Express your answer in degrees using three significant figures. ΜΠΑΣΦ 41 vec 4 → CE ? → Request Answer E ? Units O1. Assume that air resistance is proportional to speed. A parachutist falls from rest. If he did not open his parachute, he would reach a terminal velocity of 90 m/s. With an open parachute, he reaches a terminal velocity of 10 m/s. He opens his parachute 20 s after he started falling. Calculate (a) The distance already fallen at the moment when he opens his parachute; (b) The total distance fallen 40 s after he started falling.t2.2 -- (a) & (b) must be in 3rd sign. digit. units are as follow.
