A baseball is hit with a bat and, as a result, its direction is completely reversed and its speed is doubled. If the actual cont

Answer:

6.7 /s.

Step-by-step explanation:

Initial velocity = u m/s

From the question, final velocity, v = - 2u m/s

Note - (the minus sign indicates that the direction was reversed and doubled)

t = 0.45

From equation of motion,

v = u + at

Acceleration, a = (v - u)/t

= (-2u - u)/0.45

= - 3u/0.45

Acceleration, a/Original speed, u = 3/0.45

= 6.7 /s

Which equations can be used to solve for acceleration? Check all that apply.

salantis [7]

$a =\frac{v_f - v_i}{t}\\\\at = v_f -v_i\\\\\boxed{\bf{v_f =at +v_i}}\\\\\boxed{\bf{v_i = v_f-at}}$

A one day trip to new york, mary spent $6.25 for breakfast and 8.95 for lunch. She can spend no more than an average of $8.50. H

Mary spent $10.30 on dinner to stay in budget.

Step-by-step explanation:

Amount spent on breakfast = $6.25

Amount spent on lunch = $8.95

Amount spent on dinner = x

Average = $8.50

Average = $\frac{Sum\ of\ values}{No.\ of\ values}$

$8.50 = \frac{6.25+8.95+x}{3}\\8.50=\frac{15.20+x}{3}$

Multiplying both sides by 3

$8.50*3=\frac{15.20+x}{3}*3\\25.50=15.20+x\\25.50-15.20=x\\x=10.30$

Mary spent $10.30 on dinner to stay in budget.
