Answer:
The acceleration of the cart is, a = 10 m/s²
The time taken by the cart to reach 60 m, t = 3.46 s
Explanation:
Given data,
The net force acting on the cart, F = 30 N
The mass of the cart, m = 3 kg
The acceleration of the cart,
a = F / m
= 30 N / 3 kg
= 10 m/s²
The time taken by the cart to reach 60 m
S = ut + ½ at²
t = √(2S/a) (cart starts from rest)
t = √(2 x 60 /10)
t = 3.46 s
Hence, the time taken by the cart to reach 60 m, t = 3.46 s
