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.
A: Mario, a hockey player, is skating due south at a speed of 6.4 m/s relative to the ice. A teammate passes the puck to him. The puck has a speed of 11.0 m/s and is moving in a direction of 26° west of south, relative to the ice. What are the magnitude and direction (relative to due south) of the puck's velocity, as observed by Mario? B: The altitude of a hang glider is increasing at a rate of...
When it is 159 m above the ground, a rocket traveling vertically upward at a constant 8.30 m/s relative to the ground launches a secondary rocket at a speed of 12.4 m/s at an angle of 53.0 ∘ above the horizontal, both quantities being measured by an observer sitting in the rocket. Air resistance should be ignored. Part A : Just as the secondary rocket is launched, what are the horizontal and vertical components of its velocity relative to the...
A ball is kicked from flat ground with a velocity of 10 m/s at an angle of 40 degrees ccw from the horizontal. a. What are the horizontal and vertical components of the velocity just as the ball leaves the hand? b. What is the horizontal and vertical velocity of the ball when it reaches maximum height? c. At what time does the ball reach maximum vertical height? d. How far has the ball traveled vertically and horizontally at maximum...
A. A cannon is fired over level ground at an angle of 30 degrees to the horizontal. The initial velocity of the cannonball is 500 m/s but because the cannon is fired at an angle, the vertical component of the velocity is 250 m/s and the horizontal component is 433 m/s. How long is the cannonball in the air? (Use g = -10 m/s2) B. A cannon is fired over level ground at an angle of 30 degrees to the...
In the physic lab, an air-track glider of mass m is on a
frictionless air track inclined at an angle θ as is shown in the
adjacent figure.
a)- Find the acceleration of the air-track glider.
b)- supposed the air-track glider is released from rest at the
top of the incline and the distance from the glider's front bumper
to the bottom of the incline is D (or what is the same, the
distance from the top of the incline...
A 1.00-kg glider attached to a spring with a force constant 16.0 N/m oscillates on a frictionless, horizontal air track. At t = 0, the glider is released from rest at x = -2.50 cm (that is, the spring is compressed by 2.50 cm). (a) Find the period of the glider's motion. s (b) Find the maximum values of its speed and acceleration. speed m/s acceleration m/s2 (c) Find the position, velocity, and acceleration as functions of time. (Where position...
A 1.00-kg glider attached to a spring with a force constant 9.0 N/m oscillates on a frictionless, horizontal air track. At t = 0, the glider is released from rest at x = -2.80 cm (that is, the spring is compressed by 2.80 cm). (a) Find the period of the glider's motion. (b) Find the maximum values of its speed and acceleration.(c) Find the position, velocity, and acceleration as functions of time. (Where position is in m, velocity is in m/s, acceleration...
A player kicks a ball with an initial vertical velocity of 12 m/s and horizontal velocity of 16 m/s. a) At what speed does the ball hit the ground? b) For how long does the ball remain in the air? c) What maximum height is attained by the ball?
Q5: The 100kg satellite is traveling at a horizontal velocity of 10 m/s towards the right. Suddenly a meteor of mass of 50kg traveling at 200 m/s coming from the right and below with an angle of 30 measured from the vertical direction hits it! Upon impact, the meteor gets stuck with the satellite. What is the final velocity of the system satellite/meteor after impact?
