A small child throws a ball from a window 40m above the ground. If the child threw the ball with a horizontal velocity of 4m/s, how far from the base of the building does the ball land?

Acylindrical specimen of a nickel alloy having an elastic modulus of 207 gpa (30 × 106psi) and an original diameter of 10.2 mm (0.40 in.) experiences only elastic deformation when a tensile load of 8900 n (2000 lbf) is applied. compute the maximum length of the specimen before deformation if the maximum allowable elongation is 0.25 mm (0.010 in.)

A500g object falls off a cliff and losers 100 j from its gravitational potential energy store. if the gravitational field strength g=9.8n/kg, how high is the cliff?

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?
