John has tied his friend, zory, a stuffed unicorn to a toy car with a massless string whichmakes an angle of 30°. if he rides for 20 m. the weight of the unicorn is 50 n. the toy car exerts a constant force of 20 n and there is a frictional force of 10 n.
a. find the work done on the unicorn by each forces.
b. find the net work done on the unicorn.
c. if the initial velocity was 2m/s, what will be the final velocity?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
