A ball is thrown straight up with an initial velocity of 20.0 m/s. What maximum height does it reach?

Problem 2: An object is thrown from the top of a building that is 16.4 m high. The object is thrown with a velocity of 7.3 m/s. Part (a) How high above the ground does the object go? Numeric : A numeric value is expected and not an expression. h = Part (b) How long is it in the air in seconds? Numeric : A numeric value is expected and not an expression. t = Part (c) What is the velocity of the object in m/s after 0.5 s? Numeric : A numeric value is expected and not an expression. v = Part (d) What is the velocity of the object in m/s after 1.5 s? Numeric : Anumeric value is expected and not an expression. V = Part (e) What is the velocity of the object in m/s when it reaches the bottom? Numeric : A numeric value is expected and not an expression. V =

While standing on the roof of a building, a boy throws a tennis ball with an initial speed of 15 m / s at an angle of 35 ° below the horizontal. The ball lands on the ground 2.8 s later. How tall, in meters, is the building?

A ball thrown horizontally from a height of 1.2m hits the ground at a distance of 5.0m. What was the initial speed of the ball (in m/s)?

The position of a particle is r(t) = (5.0t2î – 4.0j + 6.0t³k) m. (a) What is the velocity of the particle at 0 s and at 1.0 s (in m/s)? (Express your answers in vector form.) v(0 s) m/s v(1.0 s) m/s (b) What is the average velocity between 0 s and 1.0 s (in m/s)? (Express your answer in vector form.) Vavg m/s

A helicopter starts ascending in the sky from the ground and its position is given by y = 5t^2 + 10t. After 10 seconds, a package is dropped out from the helicopter. What is the velocity of the package when it descends to a height of 10 m above the ground.

An airplane has a velocity ofv=(5m/s)i+(4m/s)jatt1=3s. For the time interval from t1=3s to t2=13s the average acceleration is a=(.5m/s2)i+(.2m/s2)j. At 13s find the magnitude and direction of the velocity of the airplane.
