A 52-kg water skier is being pulled by a speedboat. The force causes her to accelerate at 2 m/s2. Calculate the net force that causes this acceleration.
F = MA
A 52-kg water skier is being pulled by a speedboat. The force causes her to accelerate at 2 m/s2. Calculate the net force that causes this acceleration.
F = MA
F = 52 kg X 2 m/s2
A 52-kg water skier is being pulled by a speedboat. The force causes her to accelerate at 2 m/s2. Calculate the net force that causes this acceleration.
F = MA
F = 52 kg X 2 m/s2
F = 104 kg·m/s2
A 52-kg water skier is being pulled by a speedboat. The force causes her to accelerate at 2 m/s2. Calculate the net force that causes this acceleration.
F = MA
F = 52 kg X 2 m/s2
F = 104 kg·m/s2
or
F = 104 N
What is the net force on a 1,000 kg elevator accelerating at 2 m/s2.
F = MA
What is the net force on a 1,000 kg elevator accelerating at 2 m/s2.
F = MA
F = 1000 kg X 2 m/s2
What is the net force on a 1,000 kg elevator accelerating at 2 m/s2.
F = MA
F = 1000 kg X 2 m/s2
F = 2000 kg·m/s2
What is the net force on a 1,000 kg elevator accelerating at 2 m/s2.
F = MA
F = 1000 kg X 2 m/s2
F = 2000 kg·m/s2
or
F = 2000 N
What is the net force needed to accelerate a 55-kg cart at 15 m/s2.
F = MA
What is the net force needed to accelerate a 55-kg cart at 15 m/s2.
F = MA
F = 55 kg X 15 m/s2
What is the net force needed to accelerate a 55-kg cart at 15 m/s2.
F = MA
F = 55 kg X 15 m/s2
F = 825 kg·m/s2
What is the net force needed to accelerate a 55-kg cart at 15 m/s2.
F = MA
F = 55 kg X 15 m/s2
F = 825 kg·m/s2
or
F = 825 N
