- A block of mass 11.0 kg slides from rest down a frictionless 36.0° incline and is stopped by a strong spring with k = 2.30 ✕ 104 N/m. The block slides 3.00 m from the point of release to the point where it comes to rest against the spring. When the block comes to rest, how far has the spring been compressed?A block is dropped onto a spring with k = 34 N////m. The block has a speed of 3.0 m/s just before it strikes the spring. If the spring compresses an amount 0.14 m before bringing the block to rest, what is the mass of the block? Answer in kg.A child and sled with a combined mass of 32.6 kg slide down a frictionless hill, starting at the top. The sled starts from rest and acquires a speed of 6.69 m/s by the time it reaches the bottom of the hill. What is the height (in m) of the hill? Answer: m (round to the nearest hundredth)
- A 500 g particle has velocity vx = -8.0 m/s at t =-2 s. Force Fx=(4−t^2)N, where t is in s, is exerted on the particle between t=−2s and t = 2 s. This force increases from 0 N at t = -2 s to 4 N at t = 0 s and then back to 0 N at t = 2 s. What is the particle's velocity at t=2 s?A box weighing 3.9 kg is initially at rest on a horizontal floor. It is then pushed in a straight line for 1.2 m by a girl exerting a horizontal force with a magnitude 36 N. What is the final speed of the box if there if no friction between the floor and the box? What is the final speed if a coeffient 0.30 would be introduced between the floor and the box?The 1.1 kgkg physics book in figure is connected by a string to a 550 gg coffee cup. The book is given a push up the slope and released with a speed of 2.9 m/sm/s . The coefficients of friction are μsμs =0.50=0.50 and μkμk =0.20=0.20. How far does the book slide? Express your answer with the appropriate units.
- A 60.0 kg skier with an initial speed of 16.5 m/s coasts up a 2.50 m high rise as shown in the figure. Find her final speed right at the top, in meters per second, given that the coefficient of friction between her skis and the snow is 0.35.You attach a 2.10 kg weight to a horizontal spring that is fixed at one end. You pull the weight until the spring is stretched by 0.300 m and release it from rest. Assume the weight slides on a horizontal surface with negligible friction. The weight reaches a speed of zero again 0.100 s after release (for the first time after release). What is the maximum speed of the weight (in m/s)? m/s Need Help? Read It Submit AnswerA 356 g block is dropped onto a relaxed vertical spring that has a spring constant of k 1.7 N/cm. The block becomes attached to the spring and compresses the spring 12.6 cm before momentarily stopping. What is the speed of the block just before it hits the spring (assume that friction is negligible)? (Your result must be in m/s and include 1 digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take g-9.8 m/s?.)

The block slides 3.00 m from the point of release to the point where it comes to rest against the spring. When the block comes to rest, how far has the spring been compressed?A 10 kg block slides from rest down a plane inclined 30 degree with the horizontal.
