Practice Problems

Dynamics

  1. Jane is pulling her son Perrin in a sled with a horizontal force. The co-efficient of friction between the snow and the sled is 0.20 and Perrin has a mass of 15 kg. If the sled has a mass of 2.5 kg, how much force must Jane exert in order for Perrin and the sled to accelerate at a rate of 0.15 m/s2? [37 N]
  1. An elephant is pushing, with 75 000 N of force, on two jeeps that are stuck in the mud. The elephant pushes on the first jeep (which is 2000 kg (2 sd)) and it, in turn, pushes on the second jeep (which is 1500 kg). The co-efficient of friction between the jeeps and the mud is 1.9.

a)Determine the acceleration of the jeeps. [2.8 m/s2]

b)Determine the force that the heavier jeep exerts on the lighter jeep. [3.2 x 104 N]

  1. Johnny, of mass 65 kg, and Lucy, of mass 45 kg, are facing each other on roller blades. The coefficient of kinetic friction between the roller blades and concrete surface is 0.20. When Johnny pushes Lucy from rest he applies a force for 1.0 s. Lucy then slows down to a stop in another 8.0 s. Calculate:
  1. The applied force exerted by Johnny on Lucy. [790 N]
  2. How long it takes Johnny to come to rest. [5.1 s]

Kinematics

  1. Jennifer is running the 100.0 m dash at track. She accelerates at a rate of 0.88 m/s2 for the first 45 m and then maintains this speed for the remainder of the race. How long will it take her to finish the race? [16 s]
  1. Levon throws a ball straight upwards with an initial velocity of 15.0 m/s.
  2. How high will it reach? [11.5 m]
  3. How long will it take unit his friend in a tree 5.0 m above him catches the ball? (he catches the ball on its way back down) [2.7 s]

  1. Create the position-time and acceleration-time from the velocity-time graph below. Then write a story to describe the motion of the object.


Energy

  1. A Lightning McQueen (m = 750 kg) accelerates down a hill. At the top of the hill, his speed is 75 km/h and by the bottom, it is 185 km/h. The hill is 40.0 m long and makes an angle of 45.0o with the horizontal. If he has a 350 kW engine and it takes him 2.4 s to go down the hill, determine the force of friction resisting his motion. [5.6 x 103 N]
    Electricity

Solve both circuits fully.
