I throw a ball straight up in the air with a speed of 15 m/s. It leaves my hand at a height of y = 0 m. a) How high will it go? b) How long does it take to return to its initial height?
2) You throw a ball straight up with an initial velocity 15.0 m/s a) How high does it go? Ignor e the air resistance. (1 mark) b) How long does it take for the ball to reach its maximum height? (1 mark) What is the ball velocity when the ball is 6.00 m above the initial throwing point? c) (1 mark) What is the velocity of the ball when it back to initial point? (1 mark) d) 2) You throw...
A tennis player hits a ball at ground level, giving it an initial velocity of 24 m/s at 57 degrees above the horizontal. (a) what are the horizontal and verticla components of the ball;s initial velocity? (b) how high above the ground does the ball go? (c) How long does it take the ball to reach its maximum height? (d) What are the ball;s velocity and acceleration at its highest point? (e) for how long a time is the ball...
A ball is thrown straight up into the air from the ground with initial velocity v0= 4 m/s, it reaches its apex and falls back down. Neglecting air resistance, how long does it take the ball to return to the ground?
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...
throw a ball straight up into the air with initial velocity vi. (neglect air resistance). how long will it take for the ball to come back to its initial position? what is the maximum height the ball reaches?
You throw a ball upwards from the ground at an angle of above the horizontal and with an initial speed of m/s. (OK, your arm is bionic. The Blue Jays need bullpen help, they should definitely call you.) Air resistance can be neglected. a)Determine the time at which the ball reaches its peak height b) Determine the ball's peak height.
You throw a ball straight up from the ground (? = 0) with an initial speed of 20 m/s. At the same time (? = 0), another ball is dropped from a building that is 15 m high. How long will it take for the two balls to be exactly the same height off the ground?
A ball is thrown from an initial height of 3.2 m above the ground. Its initial velocity is 6.5 m/s at an angle of 22◦ above the horizontal. (a) How much time does the ball spend in the air? (b) How much time does it take for the ball to reach its maximum height? Take g = 9.81 m/s2
a ball is shot straight up into the air and its height above the ground (in feet) after t seconds is modeled by the functions s(t)=-16t+127t+8. determines the instantaneous velocity of the ball two seconds before it hit the ground 9(x) = -1x – 2+4.
