Homework Statement
A basketball player throws the ball at a 48° angle above the horizontal to a hoop whose centre is located a horizontal distance L = 4.30 m from the point of release and at a height h = 0.50 m above it. What initial speed is required if the basketball is to reach the centre...
The motion diagram below shows the position of a seat on a Ferris wheel at 12 moments. One full rotation is shown; the positions at moments 0 and 6 are labelled. For each of the following questions, choose the appropriate direction from the second diagram...
Wait I plugged in four or t and got 27.84 for theta which I then plgged into my x= r. cos (theta) formula and got 8.36 m which is not the right answer...
Homework Statement
The circular motion of a particle in the x-y plane is given by the equations: r(t)= 6.46 m, theta (t)= (6.96 rad/s) t, where r is the distance from the origin and theta is the polar angle measured counterclockwise from the positve x-axis. Calculate the x-coordinate of the...
Hi all, my homework question is this:
1. What is the angular speed in rad/s of a point on the equator of venus? (Rotation period: 243 days)
2. What is the angular speed in rad/s of a point on the surface of venus at latitude 11 degress south?
I know this isn't that difficult but I can't...
I don't really understand what you mean, so Newton's second law ( F= Ma) In the place of P (for part a))Iinput FV then in the place of F I input Ma so it looks like V= (2ma(t)/m)^ (1/2) so the m's cancel out right? then what do I do?
Homework Statement
An automobile with mass m accelerates starting from rest, while the engine supplies constant power P.
a) Show that the speed is given as a function of time by v= (2Pt/m)^(1/2)
b) Show that the acceleration is given as a function of time by a= (P/2mt)^(1/2)
c)...
