- A can of sardines is made to move along an x axis from x = 0.44 m to x = 1.49 m by a force with a magnitude given by F = e-6x, with x in meters and F in Newtons. How much work is done on the %3D can by the force?Assume that a common flea can jump straight up to a maximum height of 20 cm. If the flea has mass m = 0.5 milligrams, calculate the potential energy of the flea (in Joules, J) once it reaches its maximum height. If the flea in jumps to its maximum height but misses jumping onto a 4-legged friend, then obviously, the flea will fall to the ground. Calculate the force of gravity acting on the flea, during its free-fall to the ground? Assume that the flea falls straight down from its maximum jump height. Express the answer in Newtons.A baby is free to move on a horizontal frictionless table and is attracted to the origin by a mysterious force with magnitude F(r) = ar+Br². (i) Find the potential energy function associated with the mysterious force. (ii) If the baby is released from rest at the location (r, 0) = (a, π/4), what will be his speed when he reaches the origin? Law Application a X
- A roller coaster car travels with a speed of 2.29 m/s at point A, located 10.7m above the ground. Calculate how fast the roller coaster is moving when it reaches point D, 10.7m below point A. Assume the roller coaster is ideal and loses no energy to friction.A sled is given a push across a horizontal surface. The sled has a mass m, the push gives it an initial speed of 3.40 m/s, and the coefficient of kinetic friction between the sled and the surface is 0.150. (a) Use energy considerations to find the distance (in m) the sled moves before it stops. m (b) What If? Determine the stopping distance (in m) for the sled if its initial speed is doubled to 6.80 m/s. mUsing energy techniques solve the following problem(s)A firework cannon fires its 0.8 kg payload straight up from a starting height of 1.2 m (which is the length of the cannon) with an initial velocity of 80 m/s. (a) What is the initial gravitational potential energy of the payload relative to the ground? (b) What is the initial kinetic energy of the payload? (c) When it gets to its highest point, the payload's kinetic energy will have all been converted to gravitational potential energy. Use this knowledge and your answers from (a) and (b) to calculate the maximum height of the payload using energy techniques (instead of kinematics). Notice that we are still using the fact that the vertical velocity at its highest point is zero
- Problem 2: Suppose a car approaches a hill and has an initial speed of 108 km/h at the bottom of the hill. The driver takes her foot off of the gas pedal and allows the car to coast up the hill. a) If the car has the initial speed stated at a height of h = 0, how high, in meters, can the car coast up a hill if work done by friction is negligible? b) If, in actuality, a 770-kg car with an initial speed of 108 km/h is observed to coast up a hill and stops at a height 20.5m above its starting point, how much thermal energy was generated by friction in J?A can of beans that has mass M is launched by a springpowered device from level ground. The can is launched at an angle of a0 above the horizontal and is in the air for time T before it returns to the ground. Air resistance can be neglected. (a) How much work was done on the can by the launching device? (b) How much work is done on the can if it is launched at the same angle a0 but stays in the air twice as long? How does your result compare to the answer to part (a)?
