A diver runs horizontally off the end of a diving board with an initial speed of 2.15 m/s. ▼ Part A If the diving board is 2.50 m above the water, what is the diver's speed just before she enter Express your answer in meters per second.

Please answer this question. An airplane releases a ball as it flies parallel to the ground at a height of ℎ=245 m as shown in the figure. If the ball lands on the ground a horizontal distance equal to the height ℎ from the release point, calculate the speed ? of the plane. Neglect any effects due to air resistance, and use ?=9.81 m/s2 for the acceleration due to gravity.

A firework is launched with an initial velocity of 30 m/s at an angle of 65 degrees with respect to the horizontal.   The horizontal component of the firework’s velocity, just before it reaches the peak of its motion (where it will explode). b. The vertical component of the firework’s velocity, at a time 0.5 seconds after it was launched. c. The magnitude and direction of the acceleration of the rocket, at a time 0.5 seconds after it was launched.

The acceleration of a bus is given by a, (t) = at, where a = 1.25 m/s³ is a constant. ▾ Part A If the bus's velocity at time ₁1.15 s is 4.90 m/s, what is its velocity at time t₂ = 2.20 s?

You throw a ball up at some angle above the horizontal so that its velocity is (v0x, v0y). You then run 22.0 m forward on level ground and catch the ball 2.90 s later at the same altitude it was released from. a)  How high above the release point did the ball reach? b)  What was the horizontal component of the ball’s initial velocity, v0x? c)  What was the vertical component of the ball’s initial velocity, v0y?

a) the place where the rock lands.  b) the velocity of the rock (magnitude and direction) just before it lands.

Professional golfers can drive the ball over 200 m. While air resistance is significant, its effects are nearly canceled because lift is gained from backspin on the ball, and so a reasonable description of the ball’s trajectory is obtained if air resistance is neglected. Suppose a golfer hits a ball 200 m on level ground, giving it an initial velocity at an angle of 45o. The duration of the impact of the club and ball has been measured to be 1.00 ms. a) Calculate the velocity of the ball just after it is struck b) What is the 0.0450 kg ball's change in momentum?

A ball is kicked at an angle of 55 with initial velocity of 40 m/s. A. Find the time it takes to reach the maximum height B. Find the maximum height C. Find the horizontal distance covered by the ball after landing.

A soccer ball is kicked from the ground with an initial speed of 20.2 m/s at an upward angle of 40.9*. A player 52.8 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance.Use g=9.81 m/s?. Number i Unit
