A killer whale flips a 30kg baby seal with its tail. It exerts a force of 600N for 0.4s. If the seal is launched by the predator at an angle of 40degrees, how far from where it is launched does it land? Assume it lands at the same height it was thrown from.

A 7.7 kg firework is launched straight up and at its maximum
height 13 m it explodes into three parts. Part A (1.5 kg) moves
straight down and lands 0.23 seconds after the explosion. Part B (2
kg) moves horizontally to the right and lands 6.5 meters from Part
A. Part C moves to the left at some angle. How far from Part A does
Part C land ?(no direction needed)

(2 dimensions, 1 object, 2 accelerations) 1) A projectile is thrown with a wind. The wind produces a constant acceleration of 2 m/s/s in the same direction as the projectile’s horizontal direction. The projectile is launched with a velocity of 20 m/s at an angle of 30°. The projectile lands at the same height as it was launched. a. How far from the launch point does the projectile land? Do this problem again with no numbers. b. Calculate the range...

(a) Calculate the work function W(x) for the spring. Let U=0 when x=0. (b) An object of mass 0.900 kg on a horizontal surface is attached to this spring. The surface provides a friction force that is dependent on distance Fr(x)2x2...

1. A firework (small rocket) whose shell has a mass of m 12kg was initially on the ground before being launched to a height of 100m above the ground at which point its horizontal displacement from its starting position is 17.6m. At this location its speed is 68m/s and it's at an angle relative to (and above) the horizontal of 80 as depicted in the diagram below. Once it reaches this height it goes off and its shell splits into...

1. The determined Wile E. Coyote is still chasing the Road Runner since last week's homework. He is still strapped to the same rocket, giving him an acceleration in the x-direction of 15 m/s2. The coyote chases the Road Runner to the edge of a cliff, where the Road Runner magically continues, and the coyote goes off the cliff. The coyote velocity is completely horizontal and has a magnitude of 47.7 m/s as he goes over the edge. If the...
