hi guys haha pa tulong ako plss.

Question:

1. A 2kg toy car moves along a frictionless surface with a uniform speed og 6m/s.What is the kinetic energy?

2. Buddy, a junior highschool student,lifts a 3kg book from the floor into a cabinet 2.0m high. With reference to the floor, How much potential energy does the book acquire?..

(This is not fre p0ints )

Answer:

1. KE=36J

The kinetic energy of the 2kg toy car

along a frictionless surface would be 36J..

2. 58.88 J

The formula for P.E (potential energy) is

P.E. = m ×g xh

P.E. = m xg xh

=3 kg x 9.8 m/s* x 2.0 m

= 58.8 kg.m²/s?

= 58.8 J
