The gravitational force exerted on a baseball is 2.24 N down. A pitcher throws the ball horizontally with velocity 17.0 m/s by uniformly accelerating it along a straight horizontal line for a time interval of 183 ms. The ball starts from rest. Through what distance does it move before its release? What are the magnitude and direction of the force the pitcher exerts on the ball?

Answers

Answer 1

Answer: To have a weight of 2.21N., the ball's mass is (2.21/9.8) = .226kg.
a) d = 1/2 (vt), = 1/2 (18 x .17), = 1.53m.
b) Acceleration of the ball = (v/t), = 18/.17, = 105.88m/sec^2.
f = (ma), = .226 x 105.88, = 23.92N.

the area of a pentagon increased by 27 is the same as four times the difference of area and 15. what is the area of the pentagon?

Answers

this can be written as:
a+27=4(15-a)
now to work it out
a+27=4(15-a)
a+27=60-4a
4a+27=60
4a=33
a=8.25

hope this helps :)
