Here potential energy stored in the spring due to compression will transfered to Knightro in the form of kinetic energy.
First case,
2nd case,
1. Spring launch Knightro is learning a new trick called the ''Spring Launch'', where he stands...
A pinball machine launch ramp is constructed by placing a spring of force constant ? at the bottom of a ramp of length ? inclined at 30 degree. The spring is compressed at a distance of x= √mgL/k (sqrt mgL/k) so that when launched, the pinball (sphere of mass m and radius r) barely reaches the top of the ram without rolling back. How, suppose that the ramp is waxed, so there is no friction. Find the distance the spring...
A pinball machine launch ramp is constructed by placing a spring of force constant ? at the bottom of a ramp of length ? inclined at 30 degree. If the spring is being compressed at a distance of x= √mgL/k (sqrt mgL/k), find the ball's speed immediately after being launched.
1. A train at a constant 62.0 km/h moves east for 32.0 min, then in a direction 46.0° east of due north for 29.0 min, and then west for 42.0 min. What are the (a) magnitude and (b) angle (relative to east) of its average velocity during this trip? 2. A cart is propelled over an XX plane with acceleration components ax 5.5 m/s2 and ay = -2.3 m/s. Its initial velocity has components vox = 9.3 m/s and voy...
