A mass is stretched 4cm from equilibrium position of a spring.
If the displacement is doubled, what can be concluded about the
restoring force? A. It halved. B. Same C. Increased by 4 D.
Decreased by 4 If you know that the period of a pendulum is
1.87sec. What is the length of that pendulum? (gravity 9.81m/sec
squared) Two balls undergo inelastic collision. The y-momentum
after the collision is 98 kilogram meters/second, and the
x-momentum after the collision is 100 kilogram meters/second.
What is the magnitude of the resultant momentum after the
collision? thank you very much for your help M Bil A golf ball
is it with the initial velocity of 50.0 m/s at an angle of 55
degrees above the horizontal. (a) How high will the ball go? (b)
What is the total time the ball is in the air? (c) How far will
the ball travel horizontally before it hits the ground? To
bobpursley, the half life is 40.(potassium 40) How long will it
take for Potassium to have a 25% of oringinal radioactive
product left? In comparison to the 1
