How high does a rocket have to go above the Earth's surface until its weight is 0.3 times its weight on the Earth's surface? The radius of the earth is 6.37 x 10^6 m and the acceleration of gravity is 9.8 m/s^2. Answer in units of km.
How much equal charge should be placed on the Earth and the Moon so that the electrical repulsion balances the gravitational force of1.98 times 10^20 N? Treat the Earth and Moon as point charges a distance 3.84 times 10^8 m apart. Express your answer to three significant figures and include appropriate units.
Question #1
Recall that weight is a force and
is equal to m*g, where g is the acceleration due to gravity exerted
by the Earth near the Earth's surface. The acceleration due to
gravity exerted by the moon near the moon's surface is 16.6% that
of Earth. What is the weight (in N) of a person with a mass of 63.6
kg on the moon?_____
Question #2
Using the pulley system below, if m1=3.5 kg and
m2 = 8.4 kg,...
How much time does it take light to travel from the moon to the earth, a distance of 384000 km ? Correct answer= 1.28 secs Light from the star α Centaurus takes 4.30 years to reach the earth. What is the distance to α Centaurus in kilometers? please answer with 3 significant figures and km for units
A weight lifter lifts a 310 N set of weights from ground level to a position over his head, a vertical distance of 1.65 m. How much work does the weight lifter do, assuming he moves the weights at constant speed?
A weight lifter lifts a set of weights a vertical distance of 1.74 m. If a constant net force of 398 N is exerted on the weights, how much net work is done on the weights? Answer in units of J. The force required to stretch a Hooke's-law spring varies fr6m 0 N to 74.9 N as we stretch the spring by moving one end 14.5 cm from its unstressed position. Find the force constant of the spring. Answer in...
. In this class, we will use the value of g-10 m/s2g-10 m/s2, or g-9.8 m/s2g-9.8 m/s2, when more precision is needed. According to your textbook, what is the typical variation of gravitational acceleration gg on the surface of the Earth? The value of gg ranges from m/s2m/s2 to m/s2m/s2 . A bowling ball rolls along a straight track with an average velocity of 11 cm/s for 20 seconds. How far does the bowling ball roll in this time? The...
Your friend Suzie has a mass of 82 kg here on Earth. Use gearth = 9.8 m/s2. (a) What is her weight on Earth? 803.6 N (b) What will her mass be on a planet where the acceleration due to gravity is 6.62 m/s2? ___ kg (c) How much will she weigh on the planet referred to in part (b)? ___ N
What is the (magnitude of the) centripetal acceleration (as a multiple of g=9.8 m/s2g=9.8 m/s2) towards the Earth's axis of a person standing on the surface of the Earth at a latitude of 78.9∘78.9∘? Recall that latitude is measured from the equator, and assume the Earth's radius is 6,370 km6,370 km.
