Q1. If wind blows at 47.60 m/s over the roof of your house, what is pressure difference at the roof between inside and outside air? Use an air density of 1.29 kg/m3.
Q2. The planet Jupiter is about 320 times as massive as the Earth. Thus, it has been claimed that a person would be crushed by the force of gravity on Jupiter since people can't survive more than a few g's. Compute the number of g's a person would experience if she could stand on the equator of Jupiter. Use following astronomical data for Jupiter: mass = 1.9 multiplied by 1024 kg, equatorial radius = 7.10 multiplied by 104 km, rotation period 9 hr 55 min. Take the centripetal acceleration into account.
From what height will you have to drop the rock on Earth so that the fall-time on both planets is the same.
A glider of mass 1.00 kg is allowed to oscillate under the influence of a spring of spring constant 25.6 N/m while on a frictionless, horizontal air track. At t = 0 s glider is released from rest at x = 5.00 cm. (At equilibrium, the glider is at x = ..
You're carrying a 3.6-m-long, 25kg pole to a construction site when you decide to stop for a rest. You place one end of the pole on a fence post and hold the other end of the pole 35cm from its tip.

Mars Rover When the Mars rover was deployed on the surface of Mars in July 1998, radio signals took about 14 {rm min} to travel from Earth to the rover. How far was Mars from Earth at that time.
Each is afraid that one vine will break; as a result they grab each other and hang on. They swing upward together, reaching a point where the vines make an angle of 22.1° with the vertical. Find the value of the ratio m/M.
Charge A and charge B are 2.5 m apart. Charge A is 1.4C and charge B is 2.5C. Charge C, which is 2.0 C, is situated between them and force on charge C is zero. How far from charge A is Charge C.
