Solve each part of given problem:
Problem: The acceleration due to gravity on Mars is 3.8 m/s2.
Part A: If the Curiosity rover on Mars drops a tool from a height of 2.35 m, how long does it take to hit the ground?
Part B: If this tool were dropped on Earth from the same height, how long would it take to hit the ground?
Part C: From what height would you have to drop the tool on Earth so that the fall-time on both planets would be the same? Neglect air resistance on both Mars and the Earth.
Please use as much detail as required in solution.
Susan's 10.0kg baby brother Paul sits on a mat. Susan pulls the mat across the floor using a rope that is angled 30° above the floor. The tension is a constant 32.0N and the coefficient of friction is 0.170. Use work and energy to find Paul's s..
Two point charges q and 4q are at x=0 and x=L, respectively, and free to move. A third charge is placed so that the entire three-charge system is in static equilibrium. What is the magnitude of the third charge
An oil drop carries one excess electron and weighs 9.3 x10-15 N. What electric field strength is needed to suspend the drop so it is motionless.
It's possible to estimate the percentage of fat in the body by measuring the resistance of the upper leg rather than the upper arm; the calculation is similar. A person's leg measures 39 cm between the knee and the hip, with an average leg diamete..

On a part-time job, you are asked to bring a cylindrical iron rod of density 7800kg/m3, Calculate the weight of the rod
The solar panels on the roof of a house measure 4.0 m by 5.2 m. Assume they convert 12% of the incident EM wave's energy to electrical energy. What average power do the panels supply when the incident intensity is 1.0 kW/m2 and the panels are perpe..
A 60.0 kg pole vaulter running at 12.0 m/s vaults over the bar. Assume that the vaulter's horizontal component of velocity over the bar is 1.0 m/s and disregarding air resistance, how high was the jump?
