Look at the following case and determine which ball would bounce higher if each were thrown onto a trampoline with the given velocities. What about on concrete? Case 1: A big-time slugger hits a baseball 60 meters/sec (134 mph).
Case 2: Johnny knocks down four pins at the Bowl-a-Rena by rolling a 15-pound bowling ball 1.34 meters/sec (3 mph).

Explain your reasoning.

Use the empirical rule. the mean speed of a sample of vehicles along a stretch of highway is 70 miles per hour, with a standard deviation of 4 miles per hour. estimate the percent of vehicles whose speeds are between 66 miles per hour and 74 miles per hour. (assume the data set has a bell-shaped distribution.)

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) sketch the trajectory using an appropriate coordination system. b) how long for the projectile to reach the ground. c) how far did projectile travel horizontally before striking the ground. d) determine the projectilex & y position at t-1.3s e) determine the magnitude and direction of projectile velocity at t= 1.3s f) determine the magnitude and direction of projectile acceleration at t-1.3s
