Solve for v1
P1 + (1/2)ρv1^2 = P2 + (1/2)(v1r1^s/r2^2)^2
I am attempting to solve this equation for v1, but I am getting stuck on some algebra. How do I solve for v1? I can't figure out how to do it without eliminating v1 altogether because I have a v1^2 on both sides of the equation.
A block of mass m1=1.60kg initially moving to the right with a speed of +4.00m/s on a frictionless horizontal track collides with a spring attached to a second block of mass m2=2.10kg initially moving to the left with a speed of -2.50m/s. The spring constant is 600N/m. At the instant block 1...
Ballistic Pendulum system. Bullet weighs .00500kg and the wooden block it hits weighs 1.00kg. The increase in height is .05m. Using conservation of momentum and conservation of energy I have calculated the bullets speed at 199m/s. How can I calculate the loss in mechanical energy as a result...
deltaP equals change in P, or change in momentum. I just now noticed the quick symbols on the right. The ball is going up to the right and hits the wall at 45 degrees to the wall. The ball bounces off the wall and is going left 45 degrees from the wall.
A tennis ball of mass m=0.060kg and speed v=25m/s strikes a wall at a 45 degree angle and rebounds with the same speed at a 45 degree angle. What is the impulse (magnitude and direction)?
F=deltaP=mv=deltaP/deltaT
Not sure what I am doing wrong. mv=P so 0.060kg x 25m/s = 1.5Nm/s

A runner hopes to complete the 10,000m run in less than 30.0 minutes. After exactly 27.0 minutes, there are still 1100m to go. The runner must then accelerate at 0.20m/s^2 for how many seconds in order to achieve the desired time.
I have calculated the runner moving at 5.5m/s^2 for the...
