Jeric, a professional rooftop futbol player, kicked a 0.450 [kg] ball off a rooftop that is 81.0 [m] off the ground, at 15.0 [m/s] oriented 45.0° above his horizon. His pal, Joshua, caught the ball from a window at a distant building that is 46.0 [m] off the ground. Joshua then released the ball from this height and let the ball fall to the ground. A. What is the speed of the ball just before it reaches Joshua? В. What is the speed of the ball just before it reaches the ground? B.

Spectators watch a bicycle stunt rider travel off the end of a 57.5° ramp, rise to the top of her trajectory and, at that instant, suddenly push her bike horizontally away from her so that she falls vertically straight down, reaching the ground 0.525 s later. How far (in m) from the rider does the bicycle land if the rider has a mass mrider = 58.4 kg and the bike has a mass mbike = 14.5 kg? Neglect air resistance and assume the ground is level. ?m
The mass of a particular skateboard plus its rider is ms=78.6kg, and the skateboarder is holding a book with mass mb=3.07kg. Initially at rest, the skateboarder tosses the textbook with a velocity of vb=2.74m/s at an angle θ=24.3∘ above the horizontal, and the book is caught by a friend. Calculate the magnitude, in meters per second, of the velocity of the student. What is the magnitude, in newton seconds, of the momentum, pE, which was transferred to the the Earth during the time the book was being thrown?
A 0.160 kgkg hockey puck is moving on an icy, frictionless, horizontal surface. At tt = 0 the puck is moving to the right at 3.10 m/sm/s. Calculate the magnitude of the velocity of the puck after a force of 37.0 NN directed to the right has been applied for 0.045 ss. Express your answer with the appropriate unit What is the direction of the velocity of the puck after a force of 37.0 NN directed to the right has been applied for 0.045 ss? If instead, a force of 11.5 NN directed to the left is applied from tt = 0 to tt = 0.045 ss, what is the magnitude of the final velocity of the puck? Express your answer to two significant figures and include the appropriate units. What is the direction of the final velocity of the puck in this case?
A 1.40-kg block of wood sits at the edge of a table, 0.710 m above the floor. A 1.00×10−2-kg bullet moving horizontally with a speed of 720 m/s embeds itself within the block. What horizontal distance does the block cover before hitting the ground?
The 4 lblb particle is subjected to the action of its weight and forces F1={2i+6j−2tk}lb, F2={t2i−4tj−1k}lb , and F3={−2ti}lb, where t is in seconds. Determine the distance the ball is from the origin 4 ss after being released from rest.
A 1.5-kg playground ball is moving with a velocity of 3.0 m/s directed 30o below the horizontal just before it strikes a horizontal surface. The ball leaves this surface 0.50 s later with a velocity of 2.0 m/s directed 60o above the horizontal. What is the magnitude of the average resultant force on the ball?
During the filming of a certain movie scene, the director wants a small car (whose mass is m1) traveling due east at speed v1 to collide with a small truck (whose mass is m2) traveling north. The director also wants the collision to be arranged so that just afterward, the interlocked vehicles travel straight toward the camera. If the line between the camera and collision makes an angle of theta with respect to north, at what speed v2 should the trucker drive?
Can you help me with this problem? A bat strikes a 0.145 kg baseball. Just before impact, the ball is traveling horizontally to the right at 30.0 m/s; when it leaves the bat, the ball is traveling to the left at an angle of 30 degrees above horizontal with a speed of 38.0 m/s. The ball and bat are in contact for 1.85 ms. Find the x and y components of the average force on the ball. Suppose that the +x axis is directed to the right, and the +y axis is directed upward.
A 10 kg projectile was launched at the horizontal ground at a velocity of 20 m/s, 10 degrees with respect to the horizontal. The projectile hit a 30 kg box on top of a table at 0.177 seconds. If the box developed a speed of 5.140 m/s after impact, what is the speed of the projectile after the collision? Please include FBD.
A tall man walking at 1.10 m/s accidentally bumps his head of mass 3.07 kg on a steel doorjamb. His head stops in 0.019 s. What is the magnitude of the average force exerted by the doorjamb on the man's head?
In the very Dutch sport of Fierljeppen, athletes run up to a long pole and then use it to vault across a canal. At the very top of his arc, a 55 kg vaulter is moving at 2.5 m/s and is 5.1 m from the bottom end of the pole. What vertical force does the pole exert on the vaulter?
A small rocket for gathering weather data has a mass of 30 kg and generates 1500 N of thrust. On a windy day, the wind exerts a 20 N horizontal force on the rocket. If the rocket is launched straight up, what is the shape of its trajectory, and by how much has it been deflected sideways when it reaches a height of 1.0 km? Because the rocket goes much higher than this, assume there’s no significant mass loss during the first 1.0 km of flight.
