PHYSICS ASSIGNMENT IX CLASS
1 A bus is moving at a speed of 72 km/h. On applying brakes it
Comes to rest in 5 second. Find the acceleration and distance
covered by the bus.
2 A ball is dropped from the edge of a roof. How long does it take to
fall 4.9m? (given acceleration =9.8m/s2)
3 If a body travels along a circular path of radius 14m.calculate its
distance and displacement when it completes one rotation.
4 A body is moving with a velocity of 10m/s. If the motion is uniform
what will be the velocity after 10s.
5 Can the average velocity of a moving object be zero. Give an
example
6 A body goes round with a constant speed in a circular orbit. Is the
Motion uniform or accelerated?
7 Under what condition will the distance and distance of a moving
object will have the same magnitude?
8 Can a body at rest have acceleration?
9 A ball is thrown vertically upwards and returns to hand of the
thrower. Draw speed time graph and velocity time graph.
10 Plot velocity time graph for a uniform motion. What does the area
between the graph and time axis for a certain interval indicate.
