On a slide, a child starts sliding from rest from a height of 30 m. If...
A child and sled with a combined mass of 52.0 kg slide down a frictionless slope. If the sled starts from rest and has a speed of 3.70 m/s at the bottom, what is the height of the hill? A child and sled with a combined mass of 2.0 kg slide down a frictionless slope. If the sled starts from rest and has a speed of 3.70 m/s at the bottom, what is the height of the hill? m
A child leaves her book bag on a slide. The bag, which is at the top of the slide, starts from rest and reaches the bottom in 1.73 s. The mass of the book bag is 3, 30 kg, the length of the slide is 3.70 m and the angle of incline is 31.oe. (Assume the +x-axis to be parallel to and down the slide. For all values, enter the magnitude only.) With what acceleration does the bag go down...
A child and sled with a combined mass of 49.0 kg slide down a frictionless slope. If the sled starts from rest and has a speed of 2.40 m/s at the bottom, what is the height of the hill? m
1. )A child and sled with a combined mass of 50.0 kg slide down a frictionless slope. If the sled starts from rest and has a speed of 2.50 m/s at the bottom, what is the height of the hill? ____ m
A block of mass 0.9 kg starts from rest and slides down a curved frictionless slide. Determine the change in the block's height when its speed has reached 4.1 m/s.
A child and sled with a combined mass of 59.0 kg slide down a frictionless slope. If the sled starts from rest and has a speed of 2.00 m/s at the bottom, what is the height of the hill?
A 2 kg block starts from rest and travels 25 m down a slide from height 10 m as in the fig below. It leaves the slide with velocity 5 m/s at the bottom. What is the frictional force fk on the block?
. A 2.00kg block is moved from point A (at rest) a distance of 2.00 m to point B under the action of a variable force F(x) 10x + 6x2. Once in point B it is moving down 1.00 m through an 60.00 inclined frictionless surface until hit a spring (point C) as shown in figure. (The coefficient of kinetic friction between the block and the surface between A and B is 0.3 and the spring constant equal to 400...
E.1. [14 points) A soccer ball starts from rest when it is at a vertical height yo = 3.00 m above the ground and rolls without slipping down a curved ramp, as shown in the diagram. The ball rolls off the ramp when it is at a vertical height yı = 1.25 m above the ground. Assume the soccer ball is a hollow sphere (spherical shell) of radius 12 cm and mass 450 g. Ignore all frictional losses What is...
f 57 kg starts from rest e at a height of 45 m. h shown in Figure 9. d peak. (4.5) A 58. A ball is attached to a vertical spring with a spring constant of 6.0 N/m. It is held at the equilibrium position of the spring and then released. It falls 0.40 m and then bounces back up again. Calculate the mass of the ball. (4.7) 59. A ball of mass 0.50 kg is attached to a horizontal...
