F = m * a
F: force = 3N
m: mass = 1500g = 1.5kg
a: acceleration = __ m s⁻²
3 = (1.5) * a
3 / 1.5 = 1.5a / 1.5
a = 3/1.5
a = 2 m s⁻²
Hope this helps! :)
Answer:
MOMENTUM
Explanation:
another way of saying getting the smallest force possible is the word " MOMENTUM".
momentum is the ability to keep maintaining,incresing or itself developing to move at constant speed or to increase the speed.
Answer:
Explanation:
The initial velocity, u, of the car=15m/s
The final velocity, v, of the car =0m/s
Time, t, taken for the car to come to a stop=5s
Acceleration is calculated by,
By substitution,
The negative sign implies that the car has decelerated.
