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. 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?
A ball is kicked at ground level with an initial velocity of 18 m/s m the horizontal direction and 11 m/s in the vertical direction. At what speed doer the hall hit the pound in m/s? For how long does the ball remain in the air in seconds? What maximum height is attained by the ball in meters?
A projectile is fired from the ground level with an initial velocity that has a vertical component of 20 m/s and a horizontal component of 30 m/s. Find the range R. In the figure below, a constant external force P=160 N is applied to a 20.0 kg box, which is on a rough horizontal surface. While the force pushes the box a distance of 8.00 m, the speed changes from 0.500 m/s to 2.60 m/s. Find the work done by...
