Yes. Even greater. Air resistance or drag becomes harder the faster an object goes. This is why when cars reach their max speed they don't accelerate as fast, because they are pushing harder against the wind. If I take a tennis ball and shoot it down a bottomless pit, a 400 kph, the drag will slow the ball down till it reaches terminal velocity.
Answer:
6.0 N
Explanation:
The strength of a force is expressed as the magnitude of the force in Newton.
The formula to apply here is :
Force= mass * acceleration
F=ma
Mass, m = 4 kg
Acceleration = 1.5 m/s²
Force= 4 *1.5 = 6.0 N
