Why is it valuable to have practice observing, measuring, and predicting an object in projectile motion? The two "separate" models used in today’s experiments are both based on the same related set of kinematic equations. Why did the models not predict your measurements with the same degree of accuracy?

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
