You throw an object up with a speed of v0y = 1 m/s from a height of y = 25 m. Part (a) How long, in seconds, does it take for the object to reach the ground? Numeric : A numeric value is expected and not an expression. t = __________________________________________ Part (b) What is the object's final velocity, in meters per second, as it impacts the ground? Numeric : A numeric value is expected and not an expression. vy...
A soccer ball is kicked with an initial horizontal velocity of 20 m/s and an initial vertical velocity of 16 m/s
A soccer ball is kicked with an initial horizontal velocity of 20 m/s and an initial vertical velocity of 16 m/s. I've calculated: Initial Speed: 25.61 m/s Angle: 38.66 degrees Maximum Height it reaches: 13.06 m Distance kicked: 65.29m NOW I NEED: What is the speed of the ball 0.7 seconds after it was kicked? How high above the ground is the ball 0.7 seconds after it is kicked? help? please.

Part 1 A ball is tossed so that it bounces off the ground, rises to a height of 2.30 m, and then hits the ground again 1.70 m away from the first bounce. 1. How long is the ball in the air between the two bounces? 1.375 2. What is the ball's velocity in the x-direction? 3. What is the ball's speed just before the second bounce? 4. What is the angle of the velocity vector with respect to the...

c) A dolphin leaps out of the water at an angle of 36° above the horizontal. The horizontal component of the dolphin's velocity is 9.0 m/s. Find the magnitude of the vertical component of the velocity. d.) A golf ball rolls off a horizontal cliff with an initial speed of 12.9 m/s. The ball falls a vertical distance of 15.5 m into a lake below. How much time does the ball spend in the air? Don't do this part, I...
