To get up on the roof, a person (mass 70.0 kg) places 6.00-m aluminum ladder (mass 10.0 kg) against the house on a concrete pad with the base of ladder 2.00 m from the house. The ladder rests against a plastic rain gutter, which we can assume to frictionless. The center of ladder is 2.00 m from the bottom. The person is standing 3.00 m from the bottom. Find the normal reaction and friction forces on the ladder at its base.
Three skydivers are plummeting earthward. They are initially holding onto each other, but then push apart. Two skydivers of mass 70 and 80 kg gain horizontal velocities of 1.2 m/s north and 1.4 m/s southeast, respectively. What is the horizontal velocity of the third skydiver, whose mass is 55 kg?
The drawing shows Robin Hood(mass = 77.0 kg) about to escape froma dangerous situation. With one hand,he is gripping the rope that holds up achandelier (mass = 195 kg). When hecuts the rope where it is tied to thefloor, the chandelier will fall, and hewill b. pulled up toward a balconyabove. Ignore the friction between therope and the beams over which itslides, and find (a) the accelerationwith which Robin is pulled upward and (b) thetension in the rope while Robin escapes.
As a protest against the umpire's calls, a baseball pitcher throws a ball straight up into the air at a speed of 19.5 m/s. In the process, he moves his hand through a distance of 1.55 m. If the ball has a mass of 0.150 kg, find the force he exerts on the ball to give it this upward speed.
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 person with a mass of 80kg while dressed in a jump suit jumps from a plane while parachuting.They eventually reach a terminal speed of 60m/s. If you assume g = 10ms2 , = 1:21 kg m3 , what is the value of the product of constants cdA?
A golf ball of mass 4.50x10^-2 kg is struck by a club. Contact lasts 2.00x10^-4 s, and the ball leaves the tee with a horizontal velocity of 50.0 m/s. Compute the average force the club exerts on the ball by finding its average acceleration.
