The builders of the pyramids used a long ramp to lift 21000-kg (21-ton) blocks. If a block rose 1.0 m in height while traveling 21 m along the ramp’s surface, how much uphill force was needed to push it up the ramp at constant velocity?
1 answer
The force needed to push the block up the ramp at constant velocity is 1000 N. This can be calculated by using the equation F = m*g*sin(θ), where m is the mass of the block (21000 kg), g is the acceleration due to gravity (9.8 m/s2), and θ is the angle of the ramp (1.0 m/21 m = 0.0476 radians).
