A cannonball is shot from a cannon, at an initial height of 1.1 meters. At the peak of the trajectory, it strikes a smiley face picture, located 4.1 meters to the right. (define the i-axis to the right, and define the j-axis as up) Hint: In order to solve this, you have to understand what ''At the peak of the trajectory'' means. It means at the maximum height of the...

A block with mass m -6.8 kg is hung from a vertical spring. When the mass hangs in equilibrium, the spring stretches x 0.22 m. While at this equilibrium position, the mass is then given an initial push downward at v 4.9 m/s. The block oscillates on the spring without friction "What is the spring constant of the spring?

A charged particle of mass m = 5.1X10-8 kg, moving
with constant velocity in the y-direction enters a region
containing a constant magnetic field B = 1T aligned with the
positive z-axis as shown. The particle enters the region at (x,y) =
(0.68 m, 0) and leaves the region at (x,y) = 0, 0.68 m a time t =
863 μs after it entered the region.
