Problem 1: A baseball is thrown with 26.3 m/s at an angle of 30.6 degree above the horizontal. It is caught at the same height by another player some distance away.
What is the speed of the ball, just before it is caught? (Ignore air drag.)
Problem 2: A roach that runs for its life because you try to hit it with your physics book runs off the horizontal tabletop with a speed of 0.685 m/s. It strikes the floor a horizontal distance 0.325 m away from the edge of the table. Ignore air resistance.
What will be the vertical component of the roach's velocity just before it hits the floor?
Block 1, of mass m1 = 0.700kg , is connected over an ideal (massless and frictionless) pulley to block 2, of mass m2, Find the mass of block 2
A small, 300 {rm g} cart is moving at 1.30 {rm m/s} on an air track when it collides with a larger, 3.00 {rm kg} cart at rest. After the collision, the small cart recoils at 0.890 {rm m/s}.
Assuming the acceleration is constant during each time interval (but not necessarily the same in both intervals), illustrate what distance does the shuttle travel during the interval from 8.00s to 1.00min ?
(a) How tall is the lamp's image if the lamp is a distance of 39.6 cm from the mirror (include sign if negative)? (b) How tall is the lamp's image if the lamp is a distance of 85.8 cm from mirror (include sign if negative)?(c) How tall is the lamp..
