A bead with mass 2.20 × 102 kg is moving along a wire in the positive direction of an x axis. Beginning at time t = 0, when the bead passes through x = 0 with speed 12.0 m/s, a constant force acts on the bead. The figure indicates the bead's position at times to = 0.00 s, t₁ = 1.00 s, t₂ = 2.00 s, and t3 = 3.00 s. The bead momentarily stops at t = 3.00 s. What is the kinetic energy of the bead at t = 12.0 s? 0 Number i 5 10 x (m) Units 15 20

A bead with mass 1.80 × 10-2 kg is moving along a wire in the positive direction of an x axis. Beginning at time t = 0, when the bead passes through x = 0 with speed 12.0 m/s, a constant force acts on the bead. The figure indicates the bead's position at times t0 = 0.00 s, t1 = 1.00 s, t2 = 2.00 s, and t3 = 3.00 s. The bead momentarily stops at t = 3.00 s. What is the kinetic energy of the bead at t = 10.0 s?

A pack of four velociraptors have caught a human running through their jungle. Each raptor grabs one limb and pulls as hard as it can. One raptor exerts a force of 50.0 N at an angle of 20.0 ̊. Another exerts a force of 30.0 N at an angle of 130.0 ̊, while a third exerts a force of 90.0 N at 160.0 ̊. If the meal remains stationary, i.e. the total force is 0, at what angle and with what force is the fourth raptor pulling? Note that force is a vector. Force is measured in units called Newtons which is abbreviated N.

A frictionless plane is 10.0 m long and inclined at 33.5°. A sled starts at the bottom with an initial speed of 4.70 m/s up the incline. When it reaches the point at which it momentarily stops, a second sled is released from the top of this incline with an initial speed vi. Both sleds reach the bottom of the incline at the same moment.

An adventurous archeologist (m = 85.5 kg) tries to cross a river by swinging from a vine. The vine is 11.0 m long, and his speed at the bottom of the swing is 7.50 m/s. The archeologist doesn't know that the vine has a breaking strength of 1,000 N. Does he make it safely across the river without falling in? Yes No

The diagram shows the all of the forces acting on a body of mass 3.13 kg. The three forces have magnitudes F1 = 59.2 N, F2 = 27.7 N, and F3 = 74.4 N, with directions as indicted in the diagram, where θ = 55.8 degrees and φ = 21.4 degrees. The dashed lines are parallel to the x and y axes. At t = 0, the body is moving at a speed of 5.29 m/s in the positive x direction. 1.)What are the x and y components of the acceleration in m/s2?

A steel beam is suspended from two ropes as it is lifted to the top of a building at a constant speed. One of the ropes makes an angle of 25.2 degrees with respect to the vertical and has a tension of 722 N, while the other makes an angle of 29.5 with respect to the vertical. What is the beam's mass in kg?

A light plane of mass 1000kg makes an emergency landing on a short runway. With its engine off, it lands on the runway at a speed of 40m⋅s-1 . A hook on the plane snags a cable attached to a 120kg sandbag and drags the sandbag along. If the coefficient of friction between the sandbag and the runway is µk = 0.4, and if the plane’s brakes give an additional retarding force of magnitude 1400N, how far does the plane go before it comes to a stop?

Under the influence of its drive force, a snowmobile is moving at a constant velocity along a horizontal patch of snow. When the drive force is shut off, the snowmobile coasts to a halt. The snowmobile and its rider have a mass of 139 kg. Under the influence of a drive force of 180 N, it is moving at a constant velocity whose magnitude is 5.43 m/s. The drive force is then shut off. Find (a) the distance in which the snowmobile coasts to a halt and (b) the time required to do so. (a) S = (b) t = i i

A hockey puck with mass 0.163 kg is pushed across the ice with a constant force of 0.37 N. The coefficient of kinetic friction between the puck and the ice is 0.13. After a distance of 1.3 m, what is the puck's speed in m/s?
