Q1. John throws a baseball from the outfield from shoulder height, at an initial velocity of 29.4 m/s at an initial angle of 30.0 with respect to the horizontal. The ball is in its trajectory for a total interval of 3.00 s before the third baseman catches it at an equal shoulder-height level. (Assume air resistance negligible) What is the ball's horizontal displacement?
Q2. A 7.0-kg bowling ball experiences a net force of 5.0 N. What will be its acceleration?
Q3. As I slide a box at constant speed up a frictionless slope, pulling parallel to the slope, the tension in the rope will be:
Q4. A 500-N tightrope walker st&s at the center of the rope such that each half of the rope makes an angle of 10.0 with the horizontal. What is the tension in the rope?2 900 N
Q5. A horizontal force of 750 N is needed to overcome the force of static friction between a level floor & a 250-kg crate. If g = 9.8 m/s2, what is the coefficient of static friction?
How many 185 W lightbulbs can you use in a 191 V circuit without tripping a 15 A circuit breaker? (The bulbs are connected in parallel, which means that the potential difference across each lightbulb is 131 V.)
Find the energy, in joules, of one quantum of energy for an atomic oscillator in a block of aluminium.
Evaluate the electrostatic energy of two opposite charges
When the space shuttle (mass of the shuttle=2*10^6kg) was at the outer limit of Earth's atmosphere (distance= 350km above Earth's surface), astronauts measured the gravitational force from Earth to be equal to 1.7*10^7 newtons. Find the gravitatio..
The famous horse & cart physics scenario is explained. This scenario is used to describe why many people have a common misconception about what Newton’s 3rd Law says & does not say.
The distance between the first and fifth minimum on a screen 60 cm behind the slits is 6.0 mm. What is the wavelength of the light used in this experiment.
Ice at -13.7 °C and steam at 114 °C are brought together at atmospheric pressure in a perfectly insulated container. After thermal equilibrium is reached, the liquid phase at 43.3 °C is present. Ignoring container and equilibrium vapour pressure of t..
A baseball is hit with a speed of 33.0 ms-1 at an angle of 56.0 degrees. It land's on the flat roof of a nearby building with a height of 13 m. If the ball was hit when it was 1.7 m above the ground, what horizontal distance does it travel before it ..

A 59.0 kg skateboarder wants to just make it to the upper edge of a "quarter pipe," a track that is one-quarter of the circle with a radius of 3.80 m.
A simple pendulum in a science museum entry hall is 3.51m long, has a 1.25kg bob at its lower end, and swings with an amplitude of 10.50 degrees. How much time does the pendulum take to swing from its extreme right side to its acute left side.
A 76 g, 40-{rm cm}-long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 10 g ball of clay travelling horizontally at 2.70 m/s hits and sticks to the very bottom tip of the rod. To what maximum angle, measured fro..
