From the top of a 70 m building, you throw a ball straight up at 6 m/s. The ball misses the building on the way down.
1. What is the maximum height of the ball?
2. What is the velocity of the ball after 2 s?
3. What is the final velocity of the ball (just before it hits the ground?)
Now, the ball is thrown straight down at 6 m/s. What is the velocity of the ball after 2 s?
Using the initial velocity from part d, now what is the final velocity of the ball (just before it hits the ground)?
A laser beam passes during a slit of width1.0 cm and is pointed at the Moon, which is approximately380,000 {\rm km} from the Earth. Suppose the laser emits waves of wavelength 630 {\rm nm} (the red light of a He-Ne laser).
A rod 14 cm long is uniformly charged and has a total charge of -22 c. resolve the magnitude and direction of the electric field all along the axis of the rod at a point 36.0 cm from its center.
A student sits at rest on a piano stool that can rotate without friction. The moment of inertia of the student-stool system is 3.5 kg*m^2. Calculate the initial and final kinetic energy of the system
a model rocket launches with an initial velocity of 10 ms at an angle of 81 degrees with respect to the horizon. the
You are working for a shipping company. Your job is to stand at the bottom of a 5.9 -long ramp that is inclined at 45 above the horizontal. You grab packages off a conveyor belt and propel them up the ramp.
a uniform 2.8 magnetic field points to the right a 2.19 m long wire carrying 21.8 a is placed at an angle of 23
The drawing shows Robin Hood (mass = 76.9 kg) about to escape froma dangerous situation. With one hand, he is gripping the rope thatholds up a chandelier (mass = 224 kg). When he cuts the rope whereit is tied to the floor, the chandelier will fall..
q1. a diffraction grating is illuminated with light if wavelength 500nm. it produces the first minimum at 45 degree.
A person of mass 52.0 kg stands at rest. How much will the average force exerted on the feet by the floordiffer from the person's weight during a 0.195 s interval in which the blood's upward component of momentum increases by 4.45 10-2 kg ·
Two coils are at fixed locations. When the current in coil 2 increases at a rate of 15 A/s, the emf in coil 1 is 25 mV. Find their mutual inductance
An ?-particle has a charge of +2e and a mass of 6.64 10-27 kg. It is accelerated from rest through a potential difference that has a value of 1.38 106 V, What is the magnitude of the magnetic force on it
The greatest ocean depth yet discovered is the Marianas Trench in the western Pacific Ocean. A steel ball released at the surface requires 64 min to reach the bottom. The ball's downward acceleration is a=0.9g-cv, where g=9.81 m/s^2, and the constant..
