Question

A baseball (m=145g) traveling 37 m/s moves a fielder's glove backward 22 cm when the ball is caught. pleas explain in detail. i want to understand.

science physics

Answer 1

Answer #1

m = 145 g = 0.145 kg = mass of baseball

V_i = initial speed = 37 m/s

V_f = final speed =0

d = distance moved while slowing down = 22 cm = 0.22 m

a = acceleration

Using the equation

V_f² = V_i² + 2 a d

0² = 37² + 2 a (0.22)

a = - 3111.36 m/s²

force is given as

F = ma = 0.145 x 3111.36

F = 451.15 N

On the ride "Spindletop" at an amusement Park, people stood against the inner wall of a hollow vertical cylinder with radius 2.5 m. The cylinder begins to turn, the rider, wall, and the floor moves in unison. When the cylinder reaches a constant speed of 7.2 m/s, the floor on which the rider is drops off. The rider does not fall with it but instead is pinned against the wall. (a) What is the minimum coefficient of static friction? (b)...
