- A cannon on the surface of the Earth launches a 25.0 kg ball with a velocity of 25.0m/s at an angle of 25.0o above the horizontal. Neglecting air resistance and thecurvature of the earth, calculate:a) the distance from the cannon where the ball strikes the groundb) the maximum height to which the cannonball risesA locust jumps at an angle of 55.0 and lands 0.800 m from where it jumped. (a)What is the maximum height of the locust during its jump? Ignore air resistance andassume g = 9.8 m/s2 (b) If it jumps with the same initial speed at an angle of 45.0,would the maximum height be larger or smaller? (c) Calculate the maximum heightand range for this angle.A ball is hurled from a horizontal ground with a speed of 45 m/s at an angle of 35º from the horizontal. (a) What is the speed of the ball after 3.5 seconds? (b) How much time will it take for it to reach its highest point? (c) How much time will it take for it to reach the ground? (d) What is the maximum height reached by the ball? (e) What is the maximum horizontal distance covered by the ball?
- (a) A daredevil is attempting to jump his motorcycle over a line of buses parked end to end by driving up a 32° ramp at a speed of 40.0 m/s (144 km/h) . How many buses can he clear if the top of the takeoff ramp is at the same height as the bus tops and the buses are 20.0 m long? (b) Discuss what your answer implies about the margin of error in this act—that is, consider how much greater the range is than the horizontal distance he must travel to miss the end of the last bus. (Neglect air resistance.)3. A cannon on Earth (located at the origin) launches a projectile, of mass m, horizontally at height y = 0 m with speed vo, as shown in the figure below: y (m) ↑ x (m) Fw There is a strong wind that imparts a force with constant magnitude Fw, in the negative x-direction, on the projectile as it is airborne. VoBased on a grade 11 physics student, answer the following question: A poké-ball rolls off Ash’s table with a velocity of 1.93 m/s [horizontally]. The tabletop is 76.5 cm above the floor. If air resistance is negligible, determine how long the poké-ball is airborne the horizontal range (distance) the velocity at impact

- A box has a mass of 67 kg, a force of 91 N is applied to it at an angle of 45º, an object moves on a surface of 29 m with a coefficient of kinetic friction = 0.04 and where its initial velocity is equal to 13 meters/sec. in said path: Determine the magnitude of the normal (n).For a projectile projected horizontaly The projectile does not change its velocity along both vertical and horizontal directions. The projectile changes its velocity along both vertical and horizontal directions The projectile changes its velocity along the vertical direction but its velocity along the horizontal direction stays O constant. The projectile changes its velocity along the horizontal direction but its velocity along the vertical direction stays O constant.If the stone had been thrown front the cliff too with the same initial speed and the same angle, but above the horizontal, would it’s impact velocity be different?
