A ball is launched horizontally with speed 25m/s. If it takes 5 seconds to fall to the ground, how high up was it when it was launched? (without using the second equation of motion)

The height (in meters) of a projectile shot vertically upward from a point 4 m above ground level with an initial velocity of 25.5 m/s is h = 4 + 25.5t − 4.9t2 after t seconds.  When does the projectile meet its maximum height and what is its maximum height?

A rifle is aimed horizontally at a target 28 m away. The bullet hits the target 2.1 cm below the aiming point. What are (a) the bullet's time of flight and (b) its speed as it emerges from the rifle? (a) Number i Units (b) Number Units

An extreme sports enthusiast runs at 4 m/s horizontally as she leaps off of the 830 meter tall Burj Khalifa. When she is 200 m from the ground, she opens her parachute. How far away is she from the building when her parachute opens? Please round to the nearest meter

A person looking out the window of a stationary train notices that raindrops are falling vertically down at a speed of 3.36 m/s relative to the ground. When the train moves at a constant velocity, the raindrops make an angle of 25° when they move past the window, as the drawing shows. How fast is the train moving? Number i Units HOM 25

A stone is thrown from ground level with a speed of 10 m/s at an angle of 35° above the horizontal. How much time does it take to reach the maximum height?    (answer numerically in hundredths of a second) What is the maximum height?    (answer numerically in tenths of a meter) What is the horizontal range?   (answer numerically in tenths of a meter)

A cannonball is launched from the top of a flat mountainside, which slopes upwards at35 degrees with respect to the horizontal. The cannonball exits the cannon moving at150 m/s, at an angle of 55 degrees with respect to the horizontal.a) How much time (in seconds) elapses between the moment the cannonball isfired and the moment it lands on the mountainside.b) How far down the mountainside (in meters) does the cannonball land?

A tennis ball is struck and departs from the racket horizontally with a speed of 26.3 m/s. The ball hits the court at a horizontal distance of 18.9 m from the racket. How far above the court is the tennis ball when it leaves the racket? (a) Number i 2.47 eTextbook and Medi Units m +

A ball thrown horizontally at vi = 25.0 m/s travels a horizontal distance of d = 50.0 m before hitting the ground. From what height h was the ball thrown?

A remote-controlled car is moving around in a level (horizontal) parking lot. The velocity of the car as a function of time is given by: 3 = [5.0m/s – (0.018m/s³)t²]î + [2.0m/s + (0.55m/s²)t]j where î and ĵ are unit vectors representing two perpendicular directions on the horizontal ground (think of them as the East and North directions, if that helps you). b). What are the magnitude and direction of the car's velocity at t = 8.0 s? c). What are the magnitude and direction of the car's acceleration at t = 8.0 s? (Don't be intimated by the velocity function! Look at the î and ĵ components, and work each component separately to begin with, before combining components together to get any resultant vectors, if needed.)
