Question

a car movingwith velocitu of 29 m/s after 5sec it velocity becomes 40 m/s then calculate acceleration and force​

Answer 1

$\huge{\underline{\underline{\boxed{\sf{\purple{Answer : }}}}}}$

• Initial velocity = 30 î

• Final velocity   v=40j^

• Change in velocity  Δv=40j^−30i^

• Magnitude    ∣Δv∣=302+402=50

• Average acceleration   a=Δt∣Δv∣=1050=5 m/s2

Answer 2

Answer:

Initial velocity = 30 î

Final velocity v=40j^

Change in velocity Δv=40j^−30i^

Magnitude ∣Δv∣=302+402=50

Average acceleration a=Δt∣Δv∣=1050=5
