Question

A block of mass 2kg moving at speed of 10m/s accelerate at 3m/s for 5s. Complete its final kinetic energy

Answer 1

Explanation:

u=10 m/s a=3 t =5

thus, v=10+3*5

v= 25m/s

KE = 1/2 m v² = 1/2*2*25*25 = 625 J

Answer 2

Answer:

u=10 m/s a=3 t =5

u=10 m/s a=3 t =5thus, v=10+3*5

u=10 m/s a=3 t =5thus, v=10+3*5v= 25m/s

u=10 m/s a=3 t =5thus, v=10+3*5v= 25m/sKE = 1/2 m v² = 1/2*2*25*25 = 625 J.
