Q. As part of a safety investigation, two 1200- {rm kg} cars traveling at 24- {rm m/s} are crashed into different barriers. Find out the average forces exerted on (a) car that hits a line of water barrels and takes 1.80 {rm s} to stop, and (b) car that hits a concrete barrier and takes 0.4- {rm s} to stop.
Take the mass of the sun to be m_s = 1.99×1030 {rm kg}, gravitational constant to be G = 6.67×10-11 {rm N} cdot {rm m^2/kg^2}, and an acceleration due to gravity at the earth's surface to be g = 9.810 {rm m/s^2}.
Consider an angular motion. If the displacement is given as 250teθ, and the radius r is constant, derive the expressions for the angular velocity θ=ω, angular accelerationα, linear displacements, linear velocitytv, normal accelerationna, and tange..

A satellite is in a low circular orbit about the Earth (such as it just skims the surface of the Earth). How long does it take to make one revolution around Earth.
A steel wire of mass 0.400kg and length 0.640m supports a 102 kg block. The wire is struck exactly at its midpoint causing a small displacement. How long does it take the peak of this displacement to reach the top of the wire.
0.75 kg block of ice is sliding by you on a very slippery floor at 2.5 m/s. As it goes by, you give it a kick perpendicular to its path. Your foot is in contact with the ice block for 0.003 seconds. The block eventually slides at an angle of 22 de..
Write down an equation for the radial component
When G was first measured by Henry Cavendish, newspapers of the time hailed his experiment as "weighing Earth experiment." And Why.
The amount of internal enrgy needed to raise temperature of .25kg of water by .2 degreesCis 209.3J. How fast must a .25kg baseball travel in order for its kinetic energy to equal this internal energy.
A test rocket is fired vertically upward from a well. A catapult gives it an initial speed of 80.6m/s at ground level. Its engines then fire and it accelerates upward at 3.80 m/s2 until it reaches an altitude of 930m. At that point its engines fai..
A person who weighs 680 N is riding a 98-N mountain bike. Suppose the entire weight of the rider and bike is supported equally by the two tires. If the gauge pressure in each tire is 6.45 105 Pa, what is the area of contact between each tire and the ..
