If a 0.050kg eraser is dropped from a height of 1 meter, what is its speed just as it impacts the floor?
By
applying energy conservation, Energy at point 'a' must equal at
point 'b'. Hence, speed just as it impacts the floor comes out to
be 4.42 m/s.

A flower vase (mass=2.40kg) is dropped from a height of 1.30m and falls to the floor. what is the speed of the vase just before impact? draw a diagram showing the direction of the force on the flower vase and its displacement and show derivation of the expression for the speed of the vase just before impact . what is the power generated by the weight of the flower vase?
INCREASING TIME > 6) Consider a ball that is dropped from rest from a height of 1.0 meter above the floor. It starts at rest, then speeds up, suddenly reverses direction, and then slows as it rises. Suppose it bounces off the floor and rises back up to a height of 1.0 m (it is a super super- ball). Sketch x, y, vr, and Vy vs. time graphs of this motion (on a separate sheet ofpaper), as illustrated in the...
A soft tennis ball is dropped onto a hard floor from a height of 1.55 m and rebounds to a height of 1.03 m. (Assume that the positive direction is upward.) (a) Calculate its velocity just before it strikes the floor. (b) Calculate its velocity just after it leaves the floor on its way back up. -Answer is 4.49 m/s (c) Calculate its acceleration during contact with the floor if that contact lasts 3.50 ms. (d) How much did the...
A steel ball is dropped onto a hard floor from a height of 1.575 m and rebounds to a height of 1.3 m. Use a coordinate system in which the vertical component of velocity is positive in the upwards direction. Part (a) Calculate its velocity, in meters per second, just before it strikes the floor.
A soft tennis ball is dropped onto a hard floor from a height of 1.50 m and rebounds to a height of 1.13 m. (Assume that the positive direction is upward.) (a) Calculate its velocity just before it strikes the floor, in m/s. (b) Calculate its velocity just after it leaves the floor on its way back up, in m/s. (c) Calculate its acceleration (in m/s^2) during contact with the floor if that contact lasts 3.50 ms. (d) How much...
An object is thrown straight up from a height of one meter above the floor with an initial speed of 10 m/s. the object rises to its highest point and falls back to the floor. Plot v-vs-t and a-vs-t for this motion on separate graphs.
A soft tennis ball is dropped onto a hard floor from a height of 1.50 m and rebounds to a height of 1.10 m. (Assume that the positive direction is upward. Indicate the direction of velocities and accelerations with the sign of your answer.) (a) Calculate its velocity (in m/s) just before it strikes the floor. (b) Calculate its velocity (in m/s) just after it leaves the floor on its way back up. (c) Calculate its acceleration (in m/s2) during...
A 3 kg block is dropped from a height of 15 m. At the bottom the block hits a spring which compresses 0.5 meter and stops the block. What is the speed of the block when the spring is compressed 0.25 meters?
A 60 gram tennis ball is dropped from rest from a height of 5.0 m above the ground. A. What is the magnitude of its momentum just before the ball hits the ground if we neglect air resistance? B. What is the impulse on the tennis ball if the rebound speed just after the collision is 80% of the initial speed of the ball you used in part A?
A 290 g ball is dropped from a height of 2.2 m , bounces on a
hard floor, and rebounds to a height of 1.7 m .
(Figure 1) shows the impulse received from the floor.
What maximum force does the floor exert on the ball?
