Q2 The man stands 18 m from the wall and throws a ball at it with the speed of 15 m/s as shown in Figure Q2. He releases the ball at an angle of 0 = 30° so that it strikes the wall at B the height of h1. The ball reached the maximum height at C. (a) Find the component of velocity in x-direction just before it hit the wall at B. ([C3], ([C3], (b) Calculate is the time of flight of the ball from A to B. (c) Determine the height of hi when the ball reach and hit the wall at B. ([C4], - (d) Find the magnitude and direction of ball just before it hit the wall at B. ([C4], (e) Determine the maximum height of h2 and the horizontal distance of xc. ([C4],

A particle begins moving from rest from the origin in one-dimensional motion. It has a constant acceleration of 9 m/s2 until it reaches a position of 20 m. What is the particle's speed at 20 m? Write your answer to three significant figures. The particle's speed at 20 m is Number m/s.

This question is similar to the question above but read and calculate carefully. The situation has changed and the numbers have changed. Bonita Cart Bonita is again pulling a cart to the right. The cart used to be tied to a wall but now the rope has broken so the cart rolls over the horizontal floor without friction. Assume that the only forces on the cart are tension forces (including the force from Bonita), normal forces, and gravity with g = 9.81 m/s?. Bonita's shoes do not slide over the floor. Bonita has a mass of 52 kg. The cart has a mass of 45 kg. The mass of the rope is small enough to be ignored. Bonita is pulling the cart with a constant force of 283 newtons. Calculate the magnitude of the force that the cart exerts on Bonita. Note that the magnitude of a force is a positive quantity.

7) Sailboat travels at a speed 20.0 km/h on Georgian Bay in a direction 30.0° west of north with no land in sight while a motorboat travels 20.0° east of north at 25.0 km/h. What is velocity (magnitude and direction) of the sailboat relative to the motorboat?
