Answer:
3 m/s
Explanation:
Given:
a = 2 m/s²
Δx = 10 m
v = 7 m/s
Find: v₀
v² = v₀² + 2a (x − x₀)
(7 m/s)² = v₀² + 2 (2 m/s²) (10 m)
v₀ = 3 m/s
Given:-
- Mass of the cart (m) = 35 kg
- Speed (consider Velocity) = 1.2 m/s
To Find: Momentum of the cart.
We know,
p = mv
where,
- p = Momentum,
- m = Mass &
- v = Velocity.
Thus,
p = (35 kg)(1.2 m/s)
→ p = 42 kg m/s (Ans.)
Conclusion:-
A. ☑️ 42 kilogram - metre per second.
