Answer:
the final velocity of the cart is 30 m/s
Explanation:
Given;
initial velocity of the cart, u = 10 m/s
distance moved by the cart, d = 200 m
acceleration of the cart, a = 2.0 m/s²
The final velocity of the cart is calculated as;
v² = u² + 2ad
where;
v is the final velocity
v² = 10² + 2(2)(200)
v² = 900
v = √900
v = 30 m/s
Therefore, the final velocity of the cart is 30 m/s
