The largest and the smallest balls used in the experiment are with diameter 9.52 mm, and 2.38 mm respectively. for a glycerin with viscosity 1.5 pa. s, what is the time necessary for each ball to rich a velocity 99% of the terminal velocity? density of the ball material is given in the text. round the result to three decimal places.

Distinguish between linear momentum and angular momentum

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j.b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

Agirl throws a ball. if the ball's acceleration is 12 m/sec/sec and its mass is 0.5 kg, how much force did the girl apply to the ball?
