Hey I need help with questions 1-10. Please explain with details. Thank you

Unbalanced Force Worksheet 1. How much applied force is needed to accelerate a 2.0 kg block of wood from rest to 8.0 m/s [F] in 2.0 s along a rough table surface which results in a frictional force of 10.0 N. (18 N [F]) 2. A pilot accelerates the aircraft by increasing the thrust of the engines to 5.0 x 104 N [F] at a time when the air resistance (drag) acting on the 4.0 x 103 kg aircraft is 3.0 x 104 N [B]. By how much will the plane's speed increase in 3.5 s? (18 m/s) 3. Two children are tugging on a toy. One pulls with a force of 32 N [N] and the other pulls with a force of 30.0 N [ S]. What is the mass of the toy if the resulting acceleration is 4.0 m/s2 [N]. (0.50 kg) 4. A tennis player hits an 84 g tennis ball that is travelling 12.0 m/s [E] when it hits the racquet. The velocity is changed to 20.0 m/s [W] after being in contact with the racquet for 0.010 s. Determine the average net force applied to the ball during the stroke. (270 N [W]) 5. A swimmer releases a 20.0 kg stationary rock under water. The buoyant force acting on the rock is 150 N. Determine how long it will take the rock to fall 1.0 m. (0.93 s) 6. A nasty little boy dangles a 312 g donut on a string in front of a hungry classmate. He then jerks the string upward with a 3.80 N force as the hungry boy attempts to grab it. a. What is the net force acting on the donut? (0.742 N [Up]) b. What is the donut's acceleration? (2.38m/s2 [Up]) 7. A 1200 kg car travelling at 50 km/h [E] experiences an air resistance of 5.0 x 103 N [W] and road friction of 2200 N [W]. if the wheels are applying a force of propulsion of 7500 N [E], what is the car's velocity in 150 m? (59 km/h [E]) 8. A mover applied a force of 360 N [F] on a 50.0 kg box as it moved across the floor. The kinetic coefficient of friction is 0.69. What is the resulting acceleration of the trunk? (0.40 m/s2 [F]) 9. A boy pulls his wagon against a frictional force of 50.0 N with a kinetic coefficient of friction of 0.510. a. What is the mass of the wagon? (10.0 kg) b. Determine the applied force if the acceleration of the wagon is 2.5 m/s2 [F]. (75 N [F]) 10. A bucket of pucks (6.0 kg) slides along a skating rink at 12.5 m/s [W]. The bucket hits a rough patch of ice and experiences a frictional force of 3.0 x 101 N [E]
