The diagram shows a man pulling a child on a sledge.The acceleration of the sledge is 1.5 m/s2. The mass of the child and sledge is 38 kg. Calculate the force needed to produce this acceleration.
38 x 1.557 (N)
The sledge starts from rest and accelerates at 1.5 m/s2 until its velocity is 2.8 m/s. the time taken to reach 2.8 m/s. show that time taken to reach 2.8 m/s is about 2s pls tell with steps
2 s
The photograph shows a water skier being pulled along by a boat. what are two forces acting on the water skier
tention force and frictional force, normal force, gravitational force
The diagram shows the horizontal forces acting on the water skier. calculate the resultant force and its direction
500 – 300 = 200 (N) to the right
draw a free body diagram of a water skier being pulled along by a boat.
friction to the left. tention to the the right, normal forces, gravitational force
