Homework Statement A student gets his car stuck in a snow drift. Not at a loss, having studied physics, he attaches one end of a stout rope to the vehicle and the other end to the trunk of a nearby tree, L = 12.2 m away, allowing for a small amount of slack, W = 0.400 m. The student then...

whoa dude calm down. i appericiate the help but remember i was just asking a question, i already feel stupid enough as it is

so i set 1/2(angular accel)= 73.8+ theta final? then take the integral?

Homework Statement A shaft is turning at 73.8 rad/s at time zero. Thereafter, its angular acceleration is given by a = -10.1 rad/s2 - 4.44 t rad/s3. where t is the elapsed time. Calculate its angular speed at t = 2.58 s Homework Equations 1/2(Angular accel formula)+ 73.8t+0= theta...

Homework Statement Romeo (80.3 kg) entertains Juliet (58.0 kg) by playing his guitar from the rear of their boat at rest in still water, 2.73 m away from Juliet who is in the front of the boat. After the serenade, Juliet carefully moves to the rear of the boat (away from shore) to plant a kiss...

Homework Statement The mass of the blue (dark) puck in the figure below is 24.6% greater than the mass of the green (light) one. Before colliding, the pucks approach each other with equal and opposite momenta, and the green puck has an initial speed of 12.0 m/s. The angle q = 33.5o...

MgH=(48.7)(9.8)(14)

that would be cool to get some help instead of pointing out that I am not smart, that's why I am asking for help

Not of the outside forces

Homework Statement boy in a wheelchair (total mass, 48.7 kg) wins a race with a skateboarder. He has a speed of 1.23 m/s at the crest of a slope 2.37 m high and 14.0 m long. At the bottom of the slope, his speed is 6.27 m/s. If air resistance and rolling resistance can be modeled as a...

Homework Statement A 32.2 N child is in a swing that is attached to ropes 1.65 m long. Calculate the gravitational potential energy of the child-Earth system relative to the child's lowest position when the ropes are horizontal Homework Equations GPI=mgy Ke= 1/2 m v^2 The Attempt at a...

So then it would be the intergal of 4x?

so then the second equation would be m2g-T=-m2a?

i found that to be 9.7+ 40.95=50.65. do i take 50.65 multiplied by 3.40kg's to get the answer of the net force in Newtons?

ok so u intergrate the sum of X and Y right?
