Answer:

4589.75J

Step-by-step explanation:

Kinetic energy = 1/2 x M x v^2

Given

Mass M = 55.0kg

V = 12.92m/s

Kinetic energy

= 1/2 x 55.0 x (12.92)^2

= 1/2 x 55.0 x (12.92 x 12.92)

= 1/2 x 55.0 x 166.9

Multiply through

= 9179.5/2

= 4589.75J

A car is traveling at a constant speed of 46 miles per hour. the formula for the distance traveled at the end of t hours is d=46
jonny [76]

d = 46t

  • First, let's find "d" for 7 hours.

           d = 46(7)

           d = 322 miles                          (7, 322)

  • Next, let's find "d" for 12 hours.

            d = 46(12)

            d =   552 miles                      (12, 552)

  • Finally, let's find "d" for 18 hours.

            d = 46(18)

           d = 828 miles                          (18, 828)
