A ball is kicked with an initial speed of 40 m/s at an angle of 30 degrees from the top of a 500m cliff. How fast is the ball moving just before it hits the ground? Answer using kinematics.

A stone is thrown with an initial speed of 20 m/s at an angle of 35° above the horizontal from the top of a 53 m building. What is the speed of the rock as it strikes the ground (ignore air resistance).

A ball is thrown with a horizontal velocity of v0 from the top of an 80 m tall building. The time it takes the ball to reach the ground is: Assume that the acceleration due to gravity is 10.0 m/s^2 and ignore any effects of air resistance. Group of answer choices Less than the 4s The same as the 4s Depends on the horizontal velocity Greater than the 4s

A rock is thrown straight up into the air with an initial speed of 85 m/s at time  t = 0.  Ignore air resistance in this problem. At what times does it move with a speed of 13 m/s? Note: There are two answers to this problem.

Consider a grey squirrel falling from a tree to the ground. Use a coordinate system in which positive is downward for this problem. a) Find the squirrel’s velocity, in meters per second, just before hitting the ground when it falls from a height of 1.3 m. Ignore air resistance.  b) The squirrel softens its landing by bending its legs when it touches the ground, thereby stopping itself over a distance of 7.6 cm. Assuming a constant rate of deceleration, find the squirrel’s acceleration during this process, in meters per second squared.

A stone is thown from the top edge of a cliff with an initial speed of V0 = 15 m/s . The stone takes 3 seconds to each the bottom. What is the height of the cliff. (air resistance is negligible).

A rocket is launched from the ground with the upward velocity of 140 m/s. There is no engine working on the rocket while is is flying up. What is the maximum height the rocket reaches?

A ball is launched vertically upward from ground level at 15.0 m/s. What is its height when its speed is 5.0 m/s? O 10.2 m the ball never has a speed of 5.0 m/s 26.8 m 4.85 m 14.1 m

A car traveling in a straight line with an initial velocity of 34 m/s accelerates at a rate of 2.0 m/s2 to a velocity of 58 m/s. What is the distance covered by the car in this process?

The initial velocity of a car is 35 m/s due North.  Its final velocity is 42 m/s at 15 degrees South of East.  If this takes 30 seconds, what is the magnitude and direction of the car's average acceleration?
