Exercise: A golfer practicing on a range strikes the ball from position (3,1,1) m with an...
A ball is thrown vertically upwards with an initial velocity of 18.80 m/s, from the ground. How long is the ball in the air? (Neglect air resistance.) What is the greatest height reached by the ball? Calculate the time at which the ascending ball reaches a height of 12.8 m above the ground. A rocket, initially at rest on the ground, accelerates straight upward with a constant acceleration of 53.0 m/s^2, until the fuel is used up after 6.80s. What...
A ball is thrown directly upward and experiences no air resistance. The ball is thrown with a speed of 12 m/s. a) How long does the ball take to reach the highest point? b) How far up does the ball travel to reach the highest point? c) How fast is the ball going at half the height in b) above? d) How long does the ball take before it reaches your hand again?
thank you A ball is thrown directly upward and experiences no air resistance. The ball is thrown with a speed of 12 m/s. a) How long does the ball take to reach the highest point? b) How far up does the ball travel to reach the highest point? c) How fast is the ball going at half the height in b) above? d) How long does the ball take before it reaches your hand again?
A golfer hits a ball from a tee 4 m above the fairway. The ball leaves the club at an angle of 42° to the horizontal with a speed of 23 m.s-1 A. What maximum height (above the fairway) will the ball reach? Units: m B. From the moment it is released, how long will the ball take to reach the ground? Units: s C. Calculate the range of the ball (i.e. the distance R on the figure). Units: m
A blue ball is thrown upward with an initial speed of 22.8 m/s, from a height of 0.6 meters above the ground. 2.8 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 7.7 m/s from a height of 28.2 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2. ) What is the speed of the...
A golf ball is hit with a speed of 55 m/s at an angle of 40° to the horizontal. Neglecting air resistance (a) (5 pts.) What are the x- and y-components of the initial velocity? (b) (5 pts.) To what height does the ball rise? (c) (5 pts.) What are the magnitude and direction of the ball's velocity at the maximum height? (d) (5 pts.) What is the total time in the air? (e) (5 pts.) How far does the...
(Problem 2/10 from Meriam and Kraige Dynamics) 60 m A ball is thrown vertically up with a velocity of 36 m/s at the edge of a 60 m cliffa. Neglect air resistance and take the downward acceleration to be 9.81 m/s2, calculate: (a) the height h to which the ball rises; hNumber (b) the total time t after release for the ball to reach the bottom of the clioff tNumber (Problem 2/10 from Meriam and Kraige Dynamics) 60 m A...
A red ball is thrown down with an initial speed of 1.3 m/s from a height of 26 meters above the ground. Then, 0.4 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 23.9 m/s, from a height of 1 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2. What is the speed of the...
A ball is thrown from a height of 20 meters with an initial velocity of 10 m/s at an angle of 30° above the horizontal. Assume air resistance is negligible. (a) Find the x and y components of the ball's initial velocity. (b) What is the maximum height in meters reached by the ball? (c) For how many seconds is the ball in the air?
A ball is thrown straight upward in the air at a speed of 15.0 m/s. Ignore air resistance. a) What is the maximum height the ball will reach? b) What is the speed of the ball when it reaches 5.00 m?c) How long will the ball take to reach 5.00 m above its initial position on the way up? d) How long will the ball take to reach 5,00 m above its initial position on its way down?
