A 150 kg object's velocity increases from 6 m/s to 16 m/s in 5 s. Find its acceleration.
RRB Group D
12/10/2018 / Shift-II
2018
✓ Answer:C2 m/s²
a = (16 − 6)/5 = 2 m/s².
212
When acceleration is negative, a body's velocity ______.
RRB Group D
19/09/2018 / Shift-III
2018
✓ Answer:CDecreases
Under the source's convention of positive initial velocity, negative acceleration decreases the velocity.
213
Negative acceleration is opposite to the direction of which quantity?
RRB ALP & Technician
09/08/2018 / Shift-I
2018
✓ Answer:AVelocity
The source uses “negative acceleration” to mean retardation, which acts opposite to velocity. In general, the sign of acceleration depends on the chosen coordinate direction.
214
______ measures the change in an object's velocity per unit time.
RRB Group D
05/12/2018 / Shift-II
2018
✓ Answer:CAcceleration
Acceleration is the rate of change of velocity.
215
Which statement is true for a car moving with constant acceleration on a straight, level road?
RRB NTPC (Stage-I)
19/01/2017 / Shift-III
2017
✓ Answer:DIts velocity changes continuously.
With constant nonzero acceleration, velocity changes by equal amounts in equal time intervals.
216
A car accelerates uniformly from 18 km/h to 72 km/h in 5 s. Find its acceleration.
RRB Group D
27/09/2018 / Shift-I
2018
✓ Answer:A3 m/s²
a = (20 − 5)/5 = 3 m/s².
217
When an object moves at constant speed, what is its acceleration?
RRB Group D
01/10/2018 / Shift-II
2018
✓ Answer:CZero
The source assumes straight-line motion with constant velocity. Constant speed alone does not imply zero acceleration if direction changes.
218
A freely falling object's motion is an example of ______.
RRB Group D
25/09/2018 / Shift-III
2018
✓ Answer:CUniformly accelerated motion
Near Earth's surface and neglecting air resistance, free fall has approximately constant acceleration g.
219
A car's velocity increases uniformly from 18 km/h to 36 km/h in 5 s. Find its acceleration.
RRB Group D
04/10/2018 / Shift-I
2018
✓ Answer:B1 m/s²
18 km/h = 5 m/s and 36 km/h = 10 m/s. a = (10 − 5)/5 = 1 m/s².
220
For maximum horizontal range, what should the angle of projection be?
RRB Group D
16/11/2018 / Shift-III
2018
✓ Answer:D45°
For launch and landing at the same height without air resistance, R = u²sin(2θ)/g, maximized at θ = 45°.
