Question

43.5 kg. Shawn rides his bike 1.3 km in
10.4 min at a constant velocity.
The acceleration of gravity is 9.8 m/s^2.
What is Shawn’s kinetic energy?
Answer in units of J.

Answer 1

Answer:

K.E is 90.625 J

Explanation:

Data:

Mass = m = 43.5kg

Distance = d = 1.3km = 1300 m

Time = t = 10.4 min = 624 sec

Accelaration = a or g = 9.8

Formula for kinrtic energy

K.E = 1/2mv²

Find velocity

V = d/t = 1300/624 = 2.0833333333333 m/s

Put values in formula

K.E = 1/2 (43.5)(2.084)² = 90.624999999995
