What is the total force on an object if 47.2 pounds upward, and 59.3 lb to the right are acting on it? answer sketching the diagram and show mathematical calculation.
A diver of weight 780 N stands at the end of a diving board of length L = 5 m and negligible mass. The board is fixed to two pedestals separated by distance d = 1.5 m
An apple is dropped from a 25m cliff. At the similar time, a person at the bottom of the cliff fries an arrow up towards the apple. The arrow sticks the apple 0.450 seconds later.
Find out the magnitude of the vertical component of the velocity
An asteroid is discovered heading straight toward Earth at 14km/s. An international team manages to attach a giant rocket engine to the asteroid. The rocket fires for 10 {rm min}, after which asteroid is moving at 26^circ to its original path at a..
The fastest pitched baseball was clocked at 46 m/s. If the pitcher exerted his force (assumed to be horizontal and constant) over a distance of 1m, and a baseball has a mass of 145 g.
A tank with a volume of 0.150 m contains 27.0 degrees celcius helium gas at a pressure of 100 atm. How various balloons can be blown up if each filled balloon so a sphere 30.0 cm in diameter at 27.0 and absolute pressure of 1.20atm .
A small rocket to gather weather data is launched straight up. few seconds into the flight, its velocity is 110 and it is accelerating at 17 . At this instant, the rocket's mass is 50 and it is losing mass at the rate of 0.45 as it burns fuel.
Assume that the sun runs out of nuclear fuel & suddently collapses to form a white dwarf star, with a diameter equal to that of the Earth. Estimate the new rotation period of the Sun.
A rocket of mass 4.5 x10^5 kg is in flight. Its thrust is directed at an angle of 53° above the horizontal and has a magnitude of 6.80 x10^6 N. Find out the magnitude and direction of the rockets acceleration. Give the direction as an angle above ..
What will the force be between these charges. What should the banking angle of the curves be so that the force of the pavement on the tires of the car is in the normal direction.
A glider of mass 1.00 kg is allowed to oscillate under the influence of a spring of spring constant 25.6 N/m while on a frictionless, horizontal air track. At t = 0 s glider is released from rest at x = 5.00 cm. (At equilibrium, the glider is at x = ..
An underwater diver sees the sun 58{rm ^circ} above horizontal. How high is the sun above the horizon to a fisherman in the boat above the diver.
