Question

an object is travelling with a constant acceleration if speed of car change from 50 m s -1 to the 100 ms-1 in 10 s then find acceleration of the object​

Answer 1

Explanation:

v_1²-v_0²=2aS

0–(20)² m²/s²=2a x 50m

-400m²/s² / 100m=a

a=-4 m/s²

0²-15²=30 x 2 x a

-225=60a

a=-225/60=-3.75 m²

Answer 2

hiii yar

kaha ho
