Pig’s final kinetic energy is W1=W-W2, where W2=f*p is work of friction Ġ. W= mg*(s*sin(b) +h) pig’s ramp position is p=s +L = s + h/sin(b) ♥ pig’s potential energy above the low end of the ramp is The energy E2=E-E1 is gone on friction, that is E2=f*L is work of friction, whereį=μ*w1, w1=mg*cos(b) is component of pig’s weight normal to the aluminum ramp or ♦pig’s potential energy at vertex (when stopped) is E1=mgh ♠ kinetic energy of the pig at the moment it’s released after push-up isĮ=0.5*m*v^2, which is enough for the pig to move by itself L distance more along the ramp, where L=h/sin(b), h=50cm=0.5m, b is angle in question Speed of the pig gained after s=1.8m is v=a*t thus v^2=2as When hitting the ground, all that energy is converted to kinetic energy, so The total energy of the block on the table is: The gravitational potential energy of the block on the table is: That is also the elastic potential energy stored in the spring at maximum compression. That is also the speed of the block as it leaves the spring. In that time, the block must travel a horizontal distance of 4.59 m, so the horizontal velocity is: Time needed to fall a vertical distance of 1.9 m is: I'm sure there is some crucial information in "the figure below" !!! 3.26 your job is to calculate the launch speed. Set the two net forces equal to each other.į + (1187.76 ÷ 12.4) – 41 = 2034.645 ÷ 24.8į = 41 + (2034.645 ÷ 24.8) – (1187.76 ÷ 12.4) Your alpine rescue team is using a slingshot to send an emergency medical packet to climbers stranded on a ledge, as shown in Fig. This force and the force that the boy exerts are the forces that cause the wheelchair to accelerate. An alpine rescue team is using a slingshot to send an emergency medical packet to climbers stranded on a ledge, as shown in Fig. Let’s use the following equation to determine the acceleration. The net force on the wheelchair is equal to the sum of these two forces minus the friction force. These two forces are the component of the wheelchair’s weight that is parallel to the hill and the force the boy exerts. There are two forces that cause the wheelchair to accelerate.
