A 2kg puck is located at position (5i−2j)m with velocity (−7i-3j)m/s at time t=0s. I apply a constant force of magnitude 10N at an angle of 120° counterclockwise from the +x-axis. At time t=10s, the puck is at position (−i+10j)m with a velocity of 5m/s. My force is not the only force applied to the puck. a.How much work did I do on the puck? b.How much work is done on the puck total?

A girl of mass m1=60.0 kilograms springs from a trampoline with an initial upward velocity of vi=8.00 meters per second. At height h=2.00 meters above the trampoline, the girl grabs a box of mass m2=15.0 kilograms. For this problem, use g=9.80 meters per second per second for the magnitude of the acceleration due to gravity. What is the speed vbefore of the girl immediately before she grabs the box? What is the speed vafter of the girl immediately after she grabs the box? What is the maximum height hmax that the girl (with box) reaches? Measure hmax with respect to the top of the trampoline?
A girl throws a ball at an inclined wall from a height of 3 ft, hitting the wall at A with a horizontal velocity v0 of magnitude 25 ft/s. Knowing that the coefficient of restitution between the ball and the wall is 0.9 and neglecting friction, determine the distance d from the foot of the wall to the point B where the ball will hit the ground after bouncing off the wall.
A constant horizontal force F = 200 N is applied for a time 0.1 s by a kick to a soccer ball of mass m=0.4 kg. If the ball was initially traveling toward the player at 20 m/s, what is the speed as it leaves her foot traveling in the opposite direction?
Luke Skywalker, 73 kg, is training on Dagobah. He runs up a incline for 10 m with an average velocity of 6 mph. He then performs the same run with Yoda on his back in 4.31 s.

According to a simplified model of a mammalian heart, at each pulse approximately 20 gg of blood is accelerated from 0.22 m/sm/s to 0.36 m/sm/s during a period of 0.11 ss . What is the magnitude of the force exerted by the heart muscle?
Suppose that the 1kg standard body accelerates at 4m/s² at 160° from the +x-axis, owing two forces, one of which is F=(2.5)i+(4.6)j. What is the other force (a)in unit vector notation (b)as a magnitude and direction
A 458-gram ball is traveling horizontally at 10.8 m/s to the left when it is suddenly struck horizontally by a bat, causing it to reverse direction and to travel at 9.7 m/s to the right. If the bat produced an average force of 1,201 N on the ball, for how long was it in contact with the ball?
In the very Dutch sport of Fierljeppen, athletes run up to a long pole and then use it to vault across a canal. At the very top of his arc, a 55 kg vaulter is moving at 2.5 m/s and is 5.1 m from the bottom end of the pole. What vertical force does the pole exert on the vaulter?
A bolt gun contains a spring of spring constant k = 11 N/m which is used to shoot a bolt of mass m. The bolt leaves the gun at a speed of v = 5.4 m/s after the spring is compressed 1 cm.What is the weight, Fg in Newtons, of the bolt? What is the bolt’s speed when it hits the floor vf, in m/s, if it is fired horizontally at a height of h = 2 meters? What angle, θ in degrees, does the bolt's final velocity make with the horizontal?
A 3.00 kg box is moving to the right with speed 8.00 m/s on a horizontal, frictionless surface. At t = 0 a horizontal force is applied to the box. The force is directed to the left and has magnitude F(t)=( 6.00 N/s2 )t2 What distance does the box move from its position at t=0 before its speed is reduced to zero? If the force continues to be applied, what is the velocity of the box at 3.00 s ?
