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 it hit the ground and at what velocity does it hit the ground

The acceleration of an object (in m/s2) is given by the function a(t)=7sin(t)a(t)=7sin(t). The initial velocity of the object is v(0)=−1v(0)=-1 m/s. Round your answers to four decimal places. v(t) = -7cos(t) + 6 The objects displacement from time 0 to 3 is:   17.01216 meters Find the total distance traveled by the object from time 0 to time 3.

A bullet is shot horizontally with an initial speed of 899 m/s at a target 183 m away. How far, vertically has the bullet fallen when it hits the target? Answer in centimeters.

A projectile is launched straight up in the air. Its height​ (in feet) t seconds after launch is given by the function f(t)=−16t^2+407t+4. Find its average velocity from 2 seconds to 10.6 seconds.

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 ball is shot from the ground into the air. At a height of 7.00 m, its velocity is V = (8.00 ? + 5.00 ) m/s, with 2 horizontal and 3 upward. To what maximum height does the ball rise?

Problem 2: An object is thrown off the top of a 38-m tall building with a velocity of 350 m/s at an angle of 8.2° with respect to the horizontal. Part (a) How long is the object in the air in seconds? Numeric : A numeric value is expected and not an expression. t = Part (b) What is the maximum height the object reaches above the ground in meters? Numeric : A numeric value is expected and not an expression. hmax = Part (c) What is the horizontal distance the object covers in meters? Numeric : A numeric value is expected and not an expression. Ax =.

a student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of vo=18,5 m/s. the cliff is h=49.0 m above a flat, horizontal beach. this is a sub-par solution.  (e) How long after being released does the stone strike the beach below the cliff. give answers in seconds?. (f) with what speed and angle of impact do the stone land?  vf= in m/s 0= degree below the horizontal ( give answers in that form)

On a planet very similar to Earth, but slightly denser, where acceleration due to gravity is 10 m/s2, a projectile is fire vertically from a height of 100 meters with an initial velocity of 40 m/s. Its position above the ground after t seconds is given by h(t) = 100 + 40t − 5t2 meters. Find the maximum height the projectile attains.

A circular loop of wire lies in a plane perpendicular to a magnetic field. The magnetic field has a magnitude of 1.3 T and points out of the page as shown in the figure. The radius of the loop is 18 cm and it has a resistance of 3.2 Ω. Find the induced emf in the loop of wire if the magnetic field doubles in magnitude in 1 seconds. What is the induced current in the loop? In which direction is the induced current?
