Question is asking for the: r double dot, theta double
dot
and also, r double dot =1.98 m/s^2 and theta double
dot 0.0144 rad/s^2 are
incorrect.
Thank you!!
Car A is traveling at the constant speed of 47 km/h as it rounds the circular curve of 205-m radius and at the instant represented is at the position e traveling at the constant speed of 60 km/h and passes the center of the circle at this same instant. Car A is...
What are the angles theta 1 and theta 2 as drawn using the
momenta values after the collision?
And also show using the values before and after the collision
that the collision is Elastic

A 2.92-kg steel ball strokes a massive wall at 10.0 m/s at an angle of theta = 60.0 degree with the plane of the wall. It bounces off the wall with the same speed and angle. If the ball is in contract with the wall for 0.184 s, what is the average force existed by the wall on the ball?
Calculate the momentum of a 2200-kg elephant charging a hunter at a speed of 7.5 m/s . p e = units What is the momentum of a 0.075-kg tranquilizer dart fired at a speed of 400 m/s . p d = units What is the momentum of the 80-kg hunter running at 6.9 m/s after missing the elephant? p h = units
a 107 - kg skater with an initial speed of v=55 m/s coasts up a H=13-m-high rise as shown in the figure. The slope angle is theta=55. what is her final speed at the top? Assume the coefficient of friction between her skateboard and the ground is .185 (hint: find the distance traveled up the incline assuming a straight-line path as shown in the figure.) Use g=10 m/s^2
