Above the surface of the Earth, the magnitude of the acceleration due to gravity is inversely proportional to the square of the distance from the Earth's center. For objects falling to Earth, a = k/r2, where k is a constant and r is the distance to the center of the Earth. (a) The radius of the Earth is about 6.40×103 km. Find k using the fact that a = g at Earth's surface. (b) Find the magnitude of the acceleration due to Earth's gravity at 1.00×102 km above the surface of the Earth.
A baseball (m = 155 g) approaches a bat horizontally at the speed of 40.5 m/s (91 mi/h) and is hit straight back at a speed of 45.5 m/s (102 mi/h).
A 55 kg person is riding in a hot air balloon and scale shows this person's weight too be 549N. the acceleration of gravity at the location of the balloon is known to be 9.79 m/s/s.
A 0.7 kg block of ice is sliding by you on a very slippery floor at 3.5m/s. As it goes by, you give it a kick perpendicular to its path. Your foot is in contact with ice block for 0.003 seconds.
on one particular shot, his 1.00 g pellet gets stuck in the cheese, causing it to slide 25 cm before coming to a stop. If the muzzle velocity of the gun is 64m/s and cheese has a mass of 98 g, what is the coefficient of friction between the cheese..
A baseball is bunted down the third-base line leaving the bat from a height of 0.850m with an initial velocity of 4.00m/s at an angle of 37.87° above horizontal.
A proton is initially at rest at a point where the potential is 515V. Sometime later the proton is at a point where the potential is 190V. If no force other than the electrostatic force acts on the proton, what is its final kinetic energy.
If the aspirin could be converted completely into thermal energy, how many miles will the car go on a single tablet.
The electric motor of a model train accelerates the train from rest to 0.580 m/s in 33.0 ms. the total mass of the train is 563 g. Find out the average power delivered to the train during its acceleration. The units need to W for the final answer.
The magnitude of q is chosen to make the potential difference between spheres 430 V, with the inner sphere at higher potential. Compute q.
What is an average speed of the runner
Speedboat A negotiates a curve whose radius is 115 m. Speedboat B negotiates a curve whose radius is 194 m. Each boat experiences the same centripetal acceleration. What is the ratio vA/vB of the speeds of boats.
The top plate is illuminated by monochromatic light of wavelength 544.1 nm. Determine number of dark parallel bands crossing the top plate (including the dark band at zero thickness along the edge of contact between the two plates).
