Yes.
Neglecting air resistance, and using 9.8 m/s2 for the acceleration of gravity,
80 meters works out to 4.041 seconds (rounded).
Assuming the object free-falls, we may use:x = x0 + v0t + at2/2x0 = 0 (we determine it)v0t = 0 (dropped from rest).a = g = 10 m/st2 = 16s2.x = 10*16 / 2 = 80m.
The momentum of the spaceship is given by the product of its mass and velocity. Therefore, the velocity can be calculated by dividing the momentum by the mass of the spaceship. In this case, the magnitude of the velocity is 40 m/s to the left.
H = 1/2 G T2T2 = 2H/GT = sqrt( 2H/G ) = sqrt( 160/9.8 ) = 4.039 seconds(rounded)And if I may offer a suggestion . . . Next time you copy a question off a test or ahomework assignment, you can go ahead and drop the number '7' off the beginning.That way, it won't be so obvious, and it won't show everybody how sneaky you are.
As long as the stick remains in contact with the puck and the force on it continues,F = m AA = F/m = (40 / 0.5) = 80 m/sec2
speed of emission = wavelength per cycle * cycles per second 80 * 410 = 32,800 meters per second. (Significant figures rules may apply so 33,000 may also be a correct answer).
800
75% of 80m = 60m
80m is 3,149.6 inches / 262 feet and 5.6 inches.
8000cm=80m
8%
The length on the map that represents 80m with a scale of 1cm to 5m would be 16cm. To find this, divide 80m by 5m to get 16. Then, scale it down to one centimeter.
The area of square is : 6400.0
80 Metres = 0.08000 Kilometres
8000cm (100cm per meter).
8 000 cm There are 100 centimetres m in every metre (centi meaning hundred), So, 80m = 80 x 100 = 8 000 cm
