A plane cruising at 258 m/s accelerates at 21 m/s2 for 4.7 s. What is its final velocity? Answer in units of m/s.

How far can the center of the box be from the end of the table before the board begins to tilt?

A thin 3.00 box rests on a 6.00 board that hangs over the end of a table, as shown in the figure. How far can the center of the box be from the end of the table before the board begins to tilt?

Ball A has a mass of 1.1 kg and moves with an initial speed of 12.5 m/s. It collides with stationary balls B and C, whose centers are on a line perpendicular to the initial velocity of ball A and that are initially in contact with one-another. Balls B and C are identical and have a mass of 0.5...

A 280 block on a 56 -long string swings in a circle on a horizontal, frictionless table at 95 . what is the speed of the block?

What is the magnitude of the apparent weight of a 80 kg astronaut 5200 km from the center of the Earth's Moon in a space vehicle moving at constant velocity?

a 1200 kg car is rolling on a horizontal surface with a speed of 40 km/he when it strikes a spring-loaded guard rail. neglecting any losses due to friction, find the maximum distance the spring is compressed. assume the spring constant is 10^6 n/m.

A solid uniform disk of radius 0.250 m and mass 55.0 kg rolls down a ramp of length 4.50 m that makes an angle of 15 degrees with the horizontal. The disk starts from rest from the top of the ramp. Find a) the speed of the disk's center of mass when it reaches the bottom of the ramp and b)...

After a 0.300-kg rubber ball is dropped from a height of 1.75 m, it bounces of a concrete floor and rebounds to a height of 1.50 m. Determine the magnitude and direction of the impulse delivered

A 600 ball swings in a vertical circle at the end of a 1.2-m-long string. When the ball is at the bottom of the circle, the tension in the string is 19 .
