A space probe is descending vertically towards the surface of Mars to make a soft landing. At the instant shown (see diagram), when the probe is 400 m vertically above the surface, its speed is 40m/s. At this instant a metal object separates from the bottom of the space probe and falls freely...

what is the concept of temperature in vaccum?

A piece of aluminum (specific heat 0.910 kJ/kg 0C) of mass 175 g at 74 0 C is dropped into a Styrofoam cup filled with 183 ml water at 20 0 C. What are the final temperatures of the water and the aluminum?

A 20.0 ball is fired horizontally with initial speed toward a 110 ball that is hanging motionless from a 1.00 -long string. The balls undergo a head-on, perfectly elastic collision, after which the 110 ball swings out to a maximum angle = 51.0.

What is the minimum coefficient of friction required to maintain pure rolling motion for a disk down an inclined plane with an angle of 20.1 degrees?

A 60 kg man was bungee jumping and reached a speed of 30 m/s just before the cord began to stretch. Assume that the cord is a spring with K = 40 N/m, what is the maximum stretch in the cord (beyond its un-stretched length)

A 0.149 glider is moving to the right on a frictionless, horizontal air track with a speed of 0.840 . It has a head-on collision with a 0.303 glider that is moving to the left with a speed of 2.29 . Suppose the collision is elastic. [2:45:00 PM] Megha Shakya: Find the magnitude of the final...
